n.（名詞）
<注釋>A lobster and a locust may share a common source for their name,that is, the Latin wordlocusta, which was used for the locustand also for a crustacean that was probably a kind of lobster.We can see thatlocusta would be the source of locust, but it looks like an unlikely candidate as the source oflobster. It is thought, however, that Old Englishloppestre, the ancestor of lobster, was formed from locusta and the suffix-estre used to make agent nouns (our -ster ). The change from Latinlocusta to Old English loppestre may have been influenced by Old English loppe, meaning .spider..
龍蝦和蝗蟲的名字可能源于同一出處，即拉丁詞Locusta ， 它用于指蝗蟲，也用于表示可能是一種龍蝦的甲殼類動(dòng)物。我們可以看到，Locusta 可能是 locusa 的來(lái)源， 但不象是lobster 的來(lái)源。 但是，lobster 在古英語(yǔ)里的前身 loppestre 被認(rèn)為是由 locusta 形成的， 后綴-estre 用于組成代理者的名詞（現(xiàn)在的 -soer ）。 從拉丁文locusta 到古英語(yǔ) loppstre 的變化可能受古英語(yǔ) loppe 的影響（意為.蜘蛛.）
