Null-subject language

In linguistic typology, a null-subject language is a language whose grammar permits an independent clause to lack an explicit subject; such a clause is then said to have a null subject.

In the principles and parameters framework, the null subject is controlled by the pro-drop parameter, which is either on or off for a particular language.^{[citation needed]}

Typically, null-subject languages express person, number, and/or gender agreement with the referent on the verb, rendering a subject noun phrase redundant.

For example, in Italian the subject "she" can be either explicit or implicit:

Maria

non

not

vuole

want

mangiare.

[to-]eat

"Maria does not want to eat."

Subject

Non

not

vuole

want

mangiare.

[to-]eat

"[(S)he] does not want to eat."

The subject "(s)he" of the second sentence is only implied in Italian. English and French, on the other hand, require an explicit subject in this sentence.

Of the thousands of languages in the world, a considerable number are null-subject languages, from a wide diversity of unrelated language families. They include Albanian, Arabic, Basque, Berber, Bengali, Catalan/Valencian, Chinese, Estonian, Finnish, Galician, Gujarati, Greek, Hebrew, Hindi, Hungarian, Italian, Japanese, Korean, Maltese, Nepali, Persian, Portuguese, Punjabi, Romanian, Sindhi, Slavic languages, Spanish, Tamil and the Turkic languages, as well as most languages related to these, and many others still.

Characterization

Languages which are not null-subject languages usually require an explicit subject. English and French make an exception for the imperative mood, or where a subject is mentioned in the same sentence, one immediately preceding it, or where the subject is implied. These languages can sometimes drop pronouns in limited contexts: e.g, German for "please", Bitte, literally means "[I] beg", and in English "Not happy!" would be clearly understood as the first person singular "I am not happy". Similarly, in some cases the additional inclusion of pronouns in English has equivalent force to their optional inclusion in Spanish or Italian: e.g, "I cook, I wash up and I do the shopping" is more emphatic than simply "I cook, wash up and do the shopping".

Subjects may sometimes be dropped in colloquial speech where the subject is implied.

In the framework of government and binding theory of syntax, the term null subject refers to an empty category. The empty category in question is thought to behave like an ordinary pronoun with respect to anaphoric reference and other grammatical behavior. Hence it is most commonly referred to as "pro".

This phenomenon is similar, but not identical, to that of pro-drop languages, which may omit pronouns, including subject pronouns, but also object pronouns. While all pro-drop languages are null-subject languages, not all null-subject languages are pro-drop.

In null-subject languages that have verb inflection in which the verb inflects for person, the grammatical person of the subject is reflected by the inflection of the verb and likewise for number and gender.

Examples

The following examples come from Portuguese:

"I'm going home" can be translated either as "vou para casa" or as "eu vou para casa", where "eu" means "I".
"It's raining" can be translated as está chovendo (Brazilian Portuguese) or está a chover (European Portuguese). In Portuguese, as in most other Romance languages (but not all, French is a notable exception), there is no exact equivalent for the pronoun it. However, some older persons say Ele está a chover (European Portuguese) which directly translates to "He is raining".
"I'm going home. I'm going to watch TV" would not, except in exceptional circumstances, be translated as Eu vou para casa. Eu vou ver televisão. At least the subject of the second sentence should be omitted in Portuguese unless one wishes to express emphasis, as to emphasize the I.

As the examples illustrate, in many null-subject languages, personal pronouns exist and can be used for emphasis but are dropped whenever they can be inferred from the context. Some sentences do not allow a subject in any form while, in other cases an explicit subject without particular emphasis, would sound awkward or unnatural.

Most Bantu languages are null-subject. For example, in Ganda, 'I'm going home' could be translated as Ŋŋenze ewange or as Nze ŋŋenze ewange, where nze means 'I'.

Arabic

Arabic is considered a null-subject language, as demonstrated by the following example:

ساعِد غيرك، يساعدك

sā‘id

help

ghayrak,

other,

yusā‘iduk

helps you.

"Help another, (he) helps you."

Subject information for 'they' is encoded in the conjugation of the verb يساعد.

Azerbaijani

Gəldim,

came,

gördüm,

saw,

işğal etdim

conquered

I came, I saw, I conquered. ("Veni, vidi, vici")

Bulgarian

Дойдох,

came,

видях,

saw,

победих

conquered

I came, I saw, I conquered. ("Veni, vidi, vici")

Catalan/Valencian

In Catalan/Valencian, as in Spanish, Portuguese, Galician, etc., the subject is also encoded in the verb conjugation. Pronoun use is not obligatory.

(Nosaltres) Anem a la platja: We go to the beach.
(Tu) Ets la meva amiga: You are my friend.
(Vostès/vosaltres) No són/sou benvinguts aquí: You are not welcome here.
(Ells) Estan dormint: They are asleep.
(Jo) Necessito ajuda: I need help.
(Ell) És a la seva habitació: He is in his bedroom.
(Ella) Està cansada: She is tired.

In Catalan/Valencian, one may choose whether to use the subject or not. If used in an inclined tone, it may be seen as an added emphasis; however, in colloquial speaking, usage of a pronoun is optional. Even so, sentences with a null subject are used more frequently than sentences with a subject. In some cases, it is even necessary to skip the subject to create a grammatically correct sentence.

Chinese

Most varieties of Chinese tend to be non-null-subject. Verbs in Chinese languages are not conjugated, so it is not possible to determine the subject based on the verb alone. However, in certain circumstances, most Chinese varieties allow dropping of the subject, thus forming null-subject sentences. One of the instances where the subject would be removed is when the subject is known. Below is an example in Mandarin:

妈妈:

māma:

mother:

不

bú

Not

要

yào

want

忘

wàng

forget

了

le

PERF

丢

diū

throw

垃圾。

lāji

rubbish.

Mother: "Do not (you) forget to take out the rubbish."

妹妹:

mèimèi:

younger sister:

知道

zhīdào

(I)know

啦。

la

PTCL

Younger sister: "(I) know it."

The above example clearly shows that a speaker could omit the subject if the doer of the verb is known. In a Chinese imperative sentence, like the first text, the subject is also left out.

Galician

In Galician, as in Spanish, Portuguese, Catalan, etc., the subject is also encoded in the verb conjugation. Pronoun use is not obligatory.

(Nós) Imos á praia: We go to the beach.
(Ti) E-la miña amiga: You are my friend. (Informal singular)
(Vós) Non sodes benvidos aquí: You are not welcome here. (Informal Plural)
(Eles) Están durmindo: They are sleeping.
(Eu) Necesito axuda: I need help.
(El) Está no seu cuarto: He is in his bedroom.
(Ela) Está cansada: She is tired.

In Galician, one may choose whether to use the subject or not. If used in an inclined tone, it may be seen as an added emphasis; however, in colloquial speaking, usage of a pronoun is optional. Even so, sentences with a null subject are used more frequently than sentences with a subject. In some cases, it is even necessary to skip the subject to create a grammatically correct sentence.

Modern Greek

Ήρθα,

Írtha,

came,

είδα,

eída,

saw,

νίκησα.

níkisa.

conquered.

I came, I saw, I conquered.

"Εγώ(Egó)", which means "I",has been omitted. The conjugation has encoded them,

Hebrew

Hebrew is considered a partially null-subject language, as demonstrated by the following example:

עזור לאחרים, יעזרו לך

azor

help

l'acherim,

others,

ya'azru

will-help

l'kha

you

You help others, they will help you.

Subjects can usually be omitted only when the verb is conjugated for grammatical person, as in the third-person plural in the example above. In Hebrew one can also construct null-subject sentences as in the Latin and Turkish language examples: "We/you/they are going to the beach" can be expressed as "holkhim la-yam" (הולכים לים), lit. "Are going to the beach." This is truly a null-subject construction.

As in Spanish and Turkish, though, Hebrew conjugates verbs in accordance with specific pronouns, so "we went to the beach" is technically just as much a null-subject construction as in the other languages, but in fact the conjugation does indicate the subject pronoun: "Halakhnu la-yam" (הלכנו לים), lit. "Went (we) to the beach." The word "halakhnu" means "we went", just as the Spanish and Turkish examples indicate the relevant pronoun as the subject in their conjugation. So these should perhaps not be considered to be true null-subject phrases. Potentially confusing the issue further is the fact that Hebrew word order can also make some sentences appear to be null-subject, when the subject is in fact given after the verb. For instance, "it's raining" is expressed "yored geshem" (יורד גשם), which means "descends rain"; "rain" is the subject. The phrases meaning "It's snowing" and "It's hailing" are formed in the same way.^{[citation needed]}

Hindi

Hindi shows radical pro-drop. This type of pro-drop differs from pro-drop in languages like Spanish where pro-drop is licensed by rich verbal morphology. Radical pro-drop is possible only in NP languages.^[1] South Asian languages such as Hindi, in general, have the ability to pro-drop any and all arguments.^[2] Here, the case is expressed in a morpheme that is independent from the stem, making the pro-drop possible. ^[3]

(He/She) calls his/her parents.

The conjugations of the root verbs (faccio for fare; chiama for chiamare) already imply the subject of the sentences.

Japanese

Japanese and several other null-subject languages are topic-prominent languages; some of these languages require an expressed topic in order for sentences to make sense. In Japanese, for example, it is possible to start a sentence with a topic marked by the particle は(read as wa, written as ha) and in subsequent sentences leave the topic unstated, as it is understood to remain the same, until another one is either explicitly or implicitly introduced. For example, in the second sentence below, the subject ("we") is not expressed again but left implicit:

私達

Watashitachi

We

は

wa

TOP

買い物

kaimono

shopping

を

o

OBJ

した。

shita.

did.

後

Ato

After

で

de

COMPL

ご飯

gohan

dinner

を

o

OBJ

食べた。

tabeta.

ate.

"We went shopping. Afterwards, we ate dinner."

In other cases, the topic can be changed without being explicitly stated, as in the following example, where the topic changes implicitly from "today" to "I".

今日

Kyō

Today

は

wa

TOP

ゲーム

gēmu

game

kaō ka

whether to buy

どうか

dō ka

or not

迷っている。

mayotte iru.

confused.

"The game comes out today, but (I) can't decide whether or not to buy (it)."

It is also common for Japanese to omit things which are obvious in context. If the above line were part of a conversation about considering purchasing the game, it could be further shortened to:

発売日

Hatsubaibi

Release day

だけど、

dakedo,

but

迷っている。

mayotte iru.

not sure.

"(It's the game's) release day, but (I) can't decide (whether or not to buy it)."

Latin

Verb-conjugation endings in Latin express number and person (as well as tense and mood).

Veni,

Came-I,

vidi,

saw-I,

vici

conquered-I

I came, I saw, I conquered.

Cogito

Think-I,

ergo

therefore

sum.

am

I think, therefore I am.

Macedonian

Дојдов,

came,

видов,

saw,

победив.

conquered

I came, I saw, I conquered. ("Veni, vidi, vici")

Polish

Myślę,

(I) think,

więc

therefore

jestem.

(I) am.

I think, therefore I am. ("Cogito ergo sum")

In Polish, the subject is omitted almost every time, although it can be present to put emphasis on the subject.

Russian

Пришёл,

came,

увидел,

saw,

победил

conquered.

I came, I saw, I conquered. ("Veni, vidi, vici")

Sindhi

آيس، ڏٺم، کٽيم

āyus,

dditham,

khatiyus

I came, I saw, I conquered. ("Veni, vidi, vici")

With subjects: آئون آيس، مون ڏٺو، آئون، کٽيس
Idiomatic translation: I came, I saw, I conquered.

Spanish

In Spanish, as with Latin and most Romance languages, the subject is encoded in the verb conjugation. Pronoun use is not obligatory.

(Yo) Necesito ayuda: I need help.
(Tú) Eres mi amiga: You (informal) are my friend.
(Vos) Sos mi amiga: You (informal) are my friend.
(Usted) Me ve: You (formal) see me.
(Él) Está en su habitación: He is in his bedroom.
(Ella) Está cansada: She is tired.
(Nosotros) Vamos a la playa: We go to the beach.
(Vosotros) Deberíais andaros: You (plural, informal) should leave.
(Ustedes) No son bienvenidos aquí: You (plural) are not welcome here.
(Ellos) Están durmiendo: They are asleep.
(Ellas) Van allí: They (feminine) go there.

In Spanish, for the most part one may choose whether to use the subject or not. Generally if a subject is provided, it is either for clarity or for emphasis. Sentences with a null subject are used more frequently than sentences with a subject.

Tamil

Verb conjugations in Tamil incorporate suffixes for number (singular and plural) and person (1st, 2nd and 3rd), and also for gender (masculine, feminine and neuter) in the third person. An explicit subject, therefore, is unnecessary, and can be inferred from the verb conjugation.

Tamil script: முடிந்துவிட்டது
Transliteration: muḍinduviṭṭadu
Literal Translation: It has left, having ended.
Idiomatic Translation: It has come to an end.

Another example:

பந்தை

Pantai

Ball(ACC)

அவரிடம்

avariṭam

him(LOC)

கொடுத்தேன்

koṭuttēṉ

gave

(I) gave him the ball

Turkish

Geldim,

(I) came,

gördüm,

(I) saw,

yendim.

(I) conquered

I came, I saw, I conquered. ("Veni, vidi, vici")

Düşünüyorum,

(I) Think,

öyleyse

therefore

varım.

(I) exist.

I think, therefore I am. ("Cogito ergo sum")

Impersonal constructions

In some cases (impersonal constructions), a proposition has no referent at all. Pro-drop languages deal naturally with these, whereas many non-pro-drop languages such as English and French must fill in the syntactic gap by inserting a dummy pronoun. "*Rains" is not a correct sentence; a dummy "it" must be added: "It rains"; in French "Il pleut". In most Romance languages, however, "Rains" can be a sentence: Spanish "Llueve", Italian "Piove", Catalan "Plou", Portuguese "Chove", Romanian "Plouă", etc. Uralic and Slavic languages also show this trait: Finnish "Sataa", Hungarian "Esik"; Polish "Pada".

There are constructed languages that are not pro-drop but do not require this syntactic gap to be filled. For example, in Esperanto, "He made the cake" would translate as Li faris la kukon (never *Faris la kukon), but It rained yesterday would be Pluvis hieraŭ (not *Ĝi pluvis hieraŭ).

Null subjects in non-null-subject languages

Other languages (sometimes called non-null-subject languages) require each sentence to include a subject: this is the case for most Germanic languages, including English and German, as well as many other languages. French, though a Romance language, also requires a subject. In some cases—particularly in English, less so in German, and occasionally in French—colloquial expressions allow for the omission of the subject in a manner similar to that of Spanish or Russian:^[vague]^{[citation needed]}

"[It] Sounds good."

"[I] Bumped into George this morning."

"[We] Agreed to have a snifter to catch up on old times."

"[We] Can, must, and shall fight."

"[You] Went down to Brighton for the weekend?"

The imperative form

Even in such non-null-subject languages such as English, it is standard for clauses in the imperative mood to lack explicit subjects; for example:

"Take a break—you're working too hard."

"Shut up!"

"Don't listen to him!"

An explicit declaration of the pronoun in the imperative mood is typically reserved for emphasis:

"You stay away!"

"Don't you listen to him!"

French and German offer less flexibility with respect to null subjects.

In French, it is neither grammatically correct nor possible to include the subject within the imperative form; the vous in the expression taisez-vous stems from the fact that se taire, "to be silent," is a reflexive verb and is thus the object with similar meaning to "yourself" in an English imperative.^{[citation needed]}

In German, the pronoun (singular du or plural ihr) is normally omitted from the informal second-person imperative (Mach das, "Do it"), although it may be added in a colloquial manner for emphasis (Macht ihr das!, "You [guys] do it!"). By contrast, the addressee-specific formal imperative requires the addition of the pronoun Sie (as in Machen Sie das!, "Do it, [sir/ma'am]!") to avoid confusion with the otherwise morphologically identical infinitive, whereas the addressee-nonspecific or "neutral" formal imperative omits the pronoun and moves the verb to final position (as in Bitte nicht stören, "Please do not disturb"). On the other hand, the pronoun wir is always included in the first-person plural imperative (Machen wir das!, "Let's do it!"), with the verb appearing in first position to differentiate the imperative from the indicative mood, wherein the verb appears in second position (as in Wir machen das, "We're doing it").^[4]

Auxiliary languages

Many international auxiliary languages, while not officially pro-drop, permit pronoun omission with some regularity.

Interlingua

In Interlingua, pronoun omission is most common with the pronoun il, which means "it" when referring to part of a sentence or to nothing in particular. Examples of this word include

Il pluvia.

It's raining.

Il es ver que ille arriva deman.

It is true that he arrives tomorrow.

Il tends to be omitted whenever the contraction "it's" can be used in English. Thus, il may be omitted from the second sentence above: "Es ver que ille arriva deman". In addition, subject pronouns are sometimes omitted when they can be inferred from a previous sentence:

Illa audiva un crito. Curreva al porta. Aperiva lo.

She heard a cry. Ran to the door. Opened it.

Esperanto

Similarly, Esperanto sometimes exhibits pronoun deletion in casual use. This deletion is normally limited to subject pronouns, especially where the pronoun has been used just previously:

Ĉu

QUESTION-PARTICLE

vi

you

vidas

see

lin?

him?

Venas

Comes

nun.

now.

Do you see him? He is coming now.

In "official" use, however, Esperanto admits of null-subject sentences in two cases only:

(optional) in the 2nd person imperative (N.B. The Esperanto imperative is often named "volitive" instead, since it can be conjugated with a subject in any person, and also used in subordinate clauses)
Venu! Come!

Vi venu! You [there], come [with me]! (pronoun added for emphasis)
For "impersonal verbs" which have no semantic subject. In English or French, an "empty" subject is nevertheless required:
Pluvas. It is raining. FR: Il pleut.

Estas nun somero. It is summer now. FR: C'est l'été à présent.

Estas vere, ke li alvenos morgaŭ. It is true that he will arrive tomorrow. FR: C'est vrai qu'il arrivera demain.
(In this latter case, the sentence is not really no-subject, since "ke li alvenos morgaŭ" ("that he will arrive tomorrow") is the subject.)

Contrary to the Interlingua example above, and as in English, a repeated subject can normally be omitted only within a single sentence:

Ŝi aŭdis krion. Ŝi kuris al la pordo. Ŝi malfermis ĝin.

She heard a shout. She ran to the door. She opened it.

Ŝi aŭdis krion, kuris al la pordo kaj malfermis ĝin.

She heard a shout, ran to the door and opened it.
