The story

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’)).
