Forms
ostendō (present infinitive ostendere, perfect active ostendī, supine ostentum or ostēnsum); third conjugation[1] Perfect participle ostentum (Terence, Cato, Varro) or, later, ostēnsum.[2][3]
Etymology
It is for ⟨*obstendō⟩, from obs-, a form of ob- “before, towards”, and tendō “to stretch”.[2][1][4] De Vaan traces ⟨tendō⟩ to Proto-Italic *tend-, from Proto-Indo-European *ten-d(ʰ)- (“to stretch”).[5]
Earliest recorded meaning
The OLD's earliest citation is from Ennius, of holding out a prospect.[2] Köbler dates Ennius 204–169 BC.[6]
Semantic evolution
It meant to stretch out, hold out for inspection, show, display, as in Plautus' holding out the hands; to reveal, and to show oneself, appear, as in Terence; to point to; to bring a fact to someone's attention, mention, as in Sallust; to show a feeling or quality by one's actions; of words, to express, denote, as in Varro; to make known; to prove, demonstrate, as in Cato; to promise or threaten, as in Cicero; and to hold out a prospect, as in Ennius.[2][3] The Thesaurus notes the augural use of the old participle, as in portendō.[4]
In Ecclesiastical Latin it meant to show, display, expose.[7] English borrowed it as the rare English ostend.[1]
