-i-

Borrowed from Latin -i-.

-i-

1. (in coining neologisms) A vowel inserted interconsonantally between morphemes of Latinate origin in order to ease pronunciation (an anaptyxis, a linking vowel).

• -e-
• -o-
• -u-

• The Concise Oxford English Dictionary [Eleventh Edition] lists -i- as an entry.

The initial vowel of primate.

• USP Dictionary of USAN and International Drug Names, U.S. Pharmacopeia, 2000

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

-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)

   dutibound (duty +‎ bound)

• 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 lay → lays (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.

From Proto-Finnic *-i-, from Proto-Uralic *-j (past tense marker).
