The terms abstain and abstemious seem to have similar formats and both have meanings involving "self-restraint" or "self-denial".

Although they may appear to come from the same root and both of them start with the Latin prefix abs-, meaning "from" or "away"; abstain is traced back to abs- plus the Latin verb tenēre, "to hold"; while abstemious gets its -temious from a suffix related to the Latin noun temetum, "intoxicating drink".
