Etymology: "Autotomizing" is the present participle of "autotomize," a verb formed from "autotomy," which combines Greek "auto-" (self) and "-tomy" (cutting, from Greek "tomē," a cut). The literal sense is self-cutting, and biologists use it for an animal shedding a body part on purpose, such as a lizard dropping its tail or a crab leaving a claw behind. The word belongs to scientific vocabulary built from classical roots, so it was coined deliberately rather than passed down through speech. Its use in zoology follows the same pattern as many technical terms formed from Greek elements in the modern period. The "-ize" ending turns the noun into a verb, and the "-ing" ending makes it a participle, so "autotomizing" can describe an animal that is in the act of shedding a limb.

Synonyms: self-amputating, self-dismembering
