Still in the fishbowl (2): ‘Mackerel’
By Anatoly Liberman
Not that I can say anything quotable on the subject of the mackerel, but people keep writing about it and the attempts to understand how this fish got its name are so interesting that the story may be worth telling. Only one thing seems certain. Mackerel first appeared in a West-European text, in the French form makerels (plural) about 1140 (which means that it was known much earlier), and no one doubts that the English borrowed their word from Old or Anglo-French. From France it spread to other lands, sometimes through an intermediary. The question is why the French called the mackerel this.
