1879年,源自拉丁语 optimum,中性单数形式,意为 optimus “最好的,非常好的”(作为 bonus “好的”最高级使用),也许(Watkins)与 ops “力量,资源”有关(如果是这样,演变是从“最富有的”到“最受尊敬的”,因此来自 PIE 词根 *op- “努力工作,丰产”); 或者它与 ob “在前面”有关(de Vaan),带有最高级后缀 *-tumos.
在英语中,该词最初用于生物学,指“最有利的条件”(对于生长、代谢过程等)。作为形容词,“最好或最有利的”,从1885年开始使用。

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.
The first known use of optimum was in 1848
