masturbatory

The word 'masturbatory' is built upon the Latin verb masturbari, whose own origin is obscure but is often speculatively analyzed as a compound of manus (hand) and stuprare (to defile). The suffix -ory, descending from Latin -orius, is a productive adjectival suffix in English. Thus, the literal construction "relating to the action of masturbating" gave rise to the primary modern definition. The secondary, figurative sense of "self-absorbed" or "intellectually self-gratifying" is a metaphorical extension from the concept of self-focused, non-productive activity.

Structure: masturbat(e) (to masturbate) + ory (adjective-forming suffix) - masturbat(e): From Latin masturbatus, the past participle of masturbari (to masturbate). This functions as the core verbal root in the word. - ory: A suffix of Latin origin (-orius) used to form adjectives meaning "of, relating to, or characterized by" the action of the root verb.
