摘要：Species的语义是“物种；种类”。其拉丁语原义是a particular sort, kind, 或type。物种分类上比genus(属)小。

Species是直接从拉丁语species拿来的单词，并不是specy的复数形式。

对复数的-ies一般都读成/iz/, 但species读成 /ˈspiːʃiːz/。

Species的语义是“物种；种类”。其拉丁语原义是a particular sort, kind, 或type。物种分类上比genus(属)小。

拉丁语species源自动词specere, 后者含义为to look at, to see, behold，所以species曾有关outward appearance, shape, form。英语的species于1550s有 "appearance, outward form"之义。

Species“物种；种类”的语义可能最初源就外观特征的分类。

Species是单复同形单词(因为再加s就很难有清晰的发音)，如
