Etymology
The verb 'boost' emerged in American English around the early 19th century, with an obscure etymology. It is thought to be an alteration of a dialectal word, perhaps related to the idea of lifting or pushing from behind. The core concept has always been one of upward or forward propulsion, whether physical or figurative. The addition of the regular past tense suffix '-ed', descended from the Old English '-ode' or '-ade', transforms the base verb into its completed action form, 'boosted', indicating that the act of raising, increasing, or promoting has already occurred.
