Pronunciation: /əˈbɔːtɪv/ · Part of speech: adjective · Field: general English with specific medical uses

Definition. In its everyday sense, abortive means not successful — failing to achieve its intended result, as in an abortive attempt (an effort that does not succeed or is broken off before completion). The core idea is of something cut short or coming to nothing before it reaches its goal.

General use. Used in ordinary language, “abortive” describes plans, efforts, or actions that fail or are abandoned partway: an abortive attempt to escape, an abortive negotiation, an abortive coup. In each case the action began but did not reach a successful conclusion.

Medical uses. Within medicine, abortive carries two related but more specific meanings:

• Halting a process early. An abortive treatment or abortive therapy is one given to stop a condition before it fully develops or runs its course. For example, abortive treatment of a migraine aims to stop an attack once symptoms begin, as opposed to preventive (prophylactic) treatment, which aims to stop attacks from starting in the first place.
• Incomplete development. “Abortive” can describe a structure or process that is incompletely formed or arrested in its development — for instance, an abortive organ that has not developed fully, or an abortive infection, in which a virus enters cells but the full infectious process does not complete.

Connecting the senses. All of these uses share the same underlying notion found in the word abort: something that is stopped, broken off, or fails to reach full completion. Whether describing a failed attempt, a treatment that halts a condition early, or a structure that did not develop fully, “abortive” points to incompleteness or non-fulfilment.

Distinction from related terms. Unsuccessful and failed are general synonyms for the everyday sense. Prophylactic (preventive) contrasts with the medical sense of abortive treatment, since prophylaxis prevents a process from starting while abortive therapy stops one already begun. Rudimentary or vestigial describe incompletely or under-developed structures and overlap with one medical meaning of “abortive.”

Etymology. From Latin abortivus, from aboriri, “to miscarry” or “to fail to be born” (ab- = away, amiss + oriri = to arise, to be born) — literally, pertaining to that which fails to come to fruition.
