Part of speech: verb

Definitions

3. To generate a greater number of descendants compared to a rival population, potentially affecting species survival and adaptation

Etymology: "Outbred" is the past tense and past participle of "outbreed," which is formed from "out-" and "breed." The prefix "out-" in this sense means "beyond" or "surpassing," so to outbreed something is to breed more offspring than another group or to exceed it in breeding. The verb's base, "breed," is an ancient English word that has long meant to produce young from parents, and "out-" was attached to it to create a comparative sense of excelling in that process. A useful contrast appears in genetics and animal husbandry, where "outbreeding" describes mating between unrelated individuals, a practice opposed to inbreeding. The past forms "outbred" follow the pattern of "breed, bred, bred," so the vowel shift that marks the past tense is the same one seen in the base verb.
