語源
英語の原文（Wiktionary）
The adjective is borrowed from Latin perennis (“lasting through the whole year or for several years, perennial; continual, everlasting, perpetual”) + English -al (suffix meaning ‘of or pertaining to’ forming adjectives). Perennis is derived from per- (“completive or intensifying prefix with the sense of doing something all the way through or entirely”) + annus (“year; season, time”) (possibly ultimately from Proto-Indo-European *h₂et- (“to go”)). By surface analysis, per- + -ennial. The noun is derived from the adjective.
