biennial词源

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 -ă- becomes -ĕ-\" [Klein]. The noun meaning \"a biennial plant\" is attested by 1770.
