Etymology: "Intraspecific" is a technical coinage built from Latin roots: "intra," meaning "within," and "species," meaning "kind" or "appearance," which in Latin became the standard word for a biological kind. The adjective "intraspecific" appeared in biological writing in the early twentieth century, and it was formed in the same pattern as "interspecific," the older term for relations between different species. Scientists needed a word for how members of one species compete, vary, or interact, and this pair gave them a clean contrast. The noun "intraspecificity" follows the usual English route for turning an adjective into a noun by adding "-ity," the suffix that came into English through Old French and Latin "-itas." It is a recent formation, used mainly in ecology and evolutionary biology, so it does not have a longer history than the adjective it grows from.
