pro-lifer

The term is a modern English compound, formed in the late 20th century within the context of the abortion debate. It is built from the Latin-derived prefix 'pro-' (meaning 'for' or 'in favor of'), attached to the native English word 'life,' and completed with the agentive suffix '-er.' The construction follows a transparent and deliberate pattern, literally creating a label for "one who is for life," specifically in the political and ethical sense of advocating for the rights of the unborn fetus. Its formation mirrors other advocacy terms (e.g., 'pro-choicer') and represents a lexicalization of a political slogan into a standard noun for a partisan identity.

Structure: pro (in favor of) + life + er (agent suffix) - pro: Latin origin, a prefix meaning "in favor of, for, forward." - life: Old English origin (līf), the core noun meaning "the condition that distinguishes animals and plants from inorganic matter." - er: Old English origin, an agent noun suffix meaning "a person who/that which does something."
