vaporous

English

WOTD – 16 November 2022

Etymology

From Middle English vaporous, from Late Latin vapōrōsus (“full of steam”), from Latin vapor (“exhalation; smoke; steam, vapour”) (possibly related to Proto-Indo-European *kwep- (“to boil; to smoke, steam; aroma; strong odour”)) + -ōsus (suffix meaning ‘full of, overly, prone to’ forming adjectives from nouns). The English word is analysable as vapour +‎ -ous. Possibly a doublet of hope.
