Etymology: "Abiological" is a plain technical formation: the prefix "a-", meaning "without", attached to "biological", which itself comes from "bio-" (life) and "-logical" (relating to the study of). Together they describe something that lies outside living systems, such as a chemical or geological process that unfolds without any organism involved. The adjective is built in the same way as its close relative "abiologic," with the English suffix "-al" added to produce the adjectival form. Both words draw on the Greek "a-" and the Greek roots behind "biology," but the combination itself is modern English coinage rather than something found in classical texts, so it reflects the vocabulary of scientific writing rather than any older tradition.
