biennial (adj.)

"lasting for two years" (1620s); "occurring every two years" (1750), from Latin biennium "two-year period," from bi- (see bi-) + annus "year" (see annual). The vowel change is "due to the Latin phonetic law according to which the unaccented and closed radical syllable of the second element of compounds, original -?- becomes -?-" [Klein]. The noun meaning "a biennial plant" is attested by 1770.
