ETYMOLOGY of agog-

greek

ComponentOriginMeaning
agog- / -agogueGreek ἀγωγός (agogos), from ἄγειν (agein)“leading,” “drawing forth,” “promoting the flow of” — agentive combining form denoting induction of discharge

The word entered English in the 1600s as -agogue (noun-forming suffix), borrowed from Late Latin -agogus, from Greek ἀγωγός (agogos) — literally “leading.” The root agein (“to lead”) connects agog- to the entire directional and flow roots: cholagogue (chol- + agog- + -ue agent leading bile flow), emmenagogue (emmen- + agog- + -ue agent leading menstrual flow), and galactagogue (galact- + agog- + -ue agent leading milk production). The agentive combining form agog- is productive in pharmacology and physiology: e.g., sialagogue, hydragogue, and hemagogue.
