Etymology 3

[edit]

A word-internal spelling variant of a word-final y.

Suffix

[edit]

-i-

  1. A spelling variant of a word-final -y vowel when followed by a suffix that does not begin with an i, for example -ied, -ier, -iest.
    happiness (happy +‎ -ness)
    penniless (penny +‎ -less)
    beautiful (beauty +‎ -ful)
  2. In compound words, a spelling variant of a final or suffixed -y vowel in the first word.
    pantiliner (panty +‎ liner)
Usage notes
[edit]
  • This convention applies to any final y vowel, not just to the suffix -y. It does not apply to digraph vowels ending in y and followed by a suffix -s, for example laylays (cf. laid, lain), nor to a single-letter y vowel before a suffix such as -ing that begin with an i, for example spying (cf. spies, spied). There is no pattern predicting when the spelling change happens; for example, penniless is far more common than pennyless, but babiless is very rare.
