@datn @negative12dollarbill I agree. "Short-lived" is what's called a "possessional adjective," an adjective formed by adding an "-ed" ending to a noun and meaning "having the quality expressed by the noun." It's like the way "short-tailed" means "having a short tail." Another example is "talented." It's not the participle form of the verb "to talent," because there IS no verb "to talent"; it's a possessional adjective formed from the noun "talent," meaning "having talent." "Short-lived" is confusing because there IS a verb "to live," and also because somehow the "f" in "life" has morphed into a "v," but it's nevertheless a possessional adjective meaning "having a short life," so the vowel sound is the same as the one in "life."

But yeah, everybody gets it wrong so we'll just call that correct now. It's like the use of "literally" in the sense of "actually not literally at all," which has now been officially blessed as correct, but continues to make me so angry that smoke literally comes out of my ears.
