Abstemious and "abstain" look alike, and both have meanings involving self-restraint or self-denial. So they must both come from the same root, right? Yes and no. Both get their start from the Latin prefix abs-, meaning "from" or "away," but "abstain" traces to "abs-" plus the Latin verb tenēre (meaning "to hold"), while "abstemious" gets its "-temious" from a suffix akin to the Latin noun temetum, meaning "intoxicating drink."
1609, in the meaning defined above
borrowed from Latin abstēmius "refraining from wine, careful with one's means," from abs- (variant of ab- ab- before c- and t-) + -tēmius, from a base tēm- "intoxicating" (also in tēmētum "intoxicating beverage," tēmulentus "drunken"); if going back to an Indo-European root *temH-, akin to Sanskrit tāmyati "(he/she) is stunned, loses consciousness, is exhausted," tamayati "(he/she) chokes (someone)," Armenian tʿmrim "(he/she) is stunned" (perhaps going back to *tēmiro-)
