Forms
īnsinuō (present infinitive īnsinuāre, perfect active īnsinuāvī, supine īnsinuātum); first conjugation[1]
Etymology
It is formed from in (“into”) and sinus (“fold, bosom”), “to put into the fold”; the TLL takes it from the phrase ⟨in sinum⟩, the OLD from in- and sinuō (“to bend, curve”).[2][3] De Vaan lists it under ⟨sinus⟩, which he traces to Proto-Italic *sinu-, probably cognate with Albanian gji (“breast”); it has no further etymology.[4]
Earliest recorded meaning
De Vaan dates it from Plautus.[4] The OLD's earliest examples are from Lucretius, who writes of the sun hardly able to work its heat into houses.[3]
Semantic evolution
Its first senses are to work something in by winding ways and, with a reflexive, to make one's way in: Lucretius has a thing from outside working its way in, and the soul entering the body at birth.[3] From this came “to work oneself into favour”: Cicero warns against the cunning flatterer who insinuates himself, and tells how a man wormed his way into Metellus' friendship.[3] Seneca uses it of instilling virtue in the mind, and the jurists of making something known.[3] Post-classical writers also have the literal sense “to put into the bosom”, as Apuleius' walking with folded arms.[5][1]
Church Latin glosses it “insinuate, convey, make known, teach”.[6] English insinuate (1520s) comes from its past participle.[7]
