Nagomi latest promotion is Lobster Shabu-Shabu.
A lobster and a locust may share a common source for their name, that is, the Latin word locusta, which was used for the locust and also for a crustacean that was probably a kind of lobster.
We can see that locusta would be the source of locust, but it looks like an unlikely candidate as the source of lobster.
It is thought, however, that Old English loppestre, the ancestor of lobster, was formed from locusta and the suffix –estre used to make agent nouns (our -ster). The change from Latin locusta to Old English loppestre may have been influenced by Old English loppe, meaning “spider.”
