History and Etymology for optimum

borrowed from Latin, from neuter of optimus (earlier optumus) "best," probably originally "foremost, headmost," from ob "toward, in front of" + -tumus, -timus, superlative suffix (going back to Indo-European *-tm̥mos) — more at ob-

Note: Traditionally the initial element op- has been taken as the stem of op-, *ops "power, ability, wealth" (see opus), though superlative derivatives with -(t)imus are regularly formed from spatial prepositions (as extimus, intimus, postumus), not nouns. The inscriptional forms opitimus, opitumus probably contain an epenthetic vowel and hence would not be of etymological relevance.
