What does grampus mean?
Grampus is chiefly a literary noun for a person whose temper is sour, cantankerous, or difficult to deal with. In this use it carries a strongly evaluative tone: a grampus is not simply unhappy but actively obstructive or ungracious, and the word often suggests an irascible older person. It can also name an orca, or killer whale, especially in older English and in marine or historical contexts. The modern figurative sense is the more familiar one, while the animal sense explains the word's unusual history. Grampus ultimately comes from a phrase meaning “large fish,” linking its present reputation for formidable unpleasantness with its older use for a formidable marine animal. Because it is more expressive than neutral, writers normally reach for it when they want a vivid label rather than a precise psychological description. It remains recognizable in British and American English, though it sounds literary, humorous, or archaic rather than everyday.

Where does grampus come from?
Grampus is generally traced to French, from an expression meaning “large fish,” ultimately from Latin grandis piscis, “large fish.” The word was used for the killer whale before becoming established in English as a disparaging term for a surly or cantankerous person. Its ultimate roots, grandis and piscis, also underlie English words such as grand and fish and Latin-derived forms such as piscivorous.
