Etymology: Autotomized is the past tense and past participle of "autotomize", so the story belongs to the verb's base, which is built from two parts. "Autotomy" combines the Greek "auto-", meaning "self", with "-tomy", from the Greek "tomē", meaning "a cutting". The "-ize" ending, from Greek "-izein", turns the noun into a verb meaning to do or undergo the thing named. Put together, the word literally describes a self-cutting: an animal that cuts off its own part. The idea was applied to animals in the scientific language of the 19th and 20th centuries, when naturalists needed precise terms for behaviours they were observing. Lizards that drop their tails when seized, and crabs that release a claw, are the classic examples. Because the coinage is technical rather than ancient, the Greek parts were assembled by modern biologists rather than handed down from classical writers.

Synonyms: self-mutilated, self-shedding
