aye-aye

Where does the word "aye-aye" come from? It comes from Malagasy hai-hai, passing through French before entering English (1800s).

Aye-aye’s story begins in Malagasy: hai-hai meant “an avoidance name for a rare nocturnal lemur.” Malagasy communities traditionally avoided naming this feared, taboo nocturnal animal directly. By 1780s, the word had taken hold in French as aye-aye. French naturalist Sonnerat recorded the Malagasy name while cataloguing Madagascar's wildlife. It reached English by 1800s as aye-aye. Entered English zoological vocabulary alongside French natural-history accounts. Today, aye-aye means a rare, nocturnal lemur native to Madagascar, notable for its large eyes, rodent-like teeth, and long, thin middle finger used to extract grubs from wood.
