lobster (English)

Where does "lobster" come from?

The word 'lobster' is rooted in the Old English 'loppestre,' which combined the suffix '-estre' with either the word for a spider or, more likely, a corruption of the Latin 'locusta,' meaning 'grasshopper' or 'locust.' While the historical crustacean sense refers to a creature once called a 'sea-grasshopper,' the modern colloquial sense of 'lobster' to describe a sunburned person captures the visual shift from the animal's natural color to its vibrant, cooked hue.
