Forms

simulātiō f (genitive simulātiōnis); third declension[1]

Etymology

It is formed from Latin simulō (“to imitate, pretend”) + -tiō.[2][1][3] The verb comes from similis (“like”), which de Vaan traces to Proto-Italic *semali- (“alike, together”) and Proto-Indo-European *smh₂-el-i-, cognate with Old Irish samail (“likeness”) and Ancient Greek ὁμαλός (homalós, “even, level”).[4]

Earliest recorded meaning

De Vaan gives Terence as its first author.[4] In the Heauton Timorumenos a man protests nōn mea'st simulātiō, “pretending is not my way”.[2]

Semantic evolution

It is the putting on of an appearance, pretence, and in rhetoric feigned feeling;[2] Cicero has a man who hid great wisdom under a show of folly.[2] It is also a pretext: Cicero asks whether armies are sent against the enemy or, on that pretext, against allies, and per simulātiōnem is “under pretence”.[2] Seneca uses it of a mirror's copying of another's colour.[2] Lewis and Short give it the further senses of insincerity and hypocrisy.[5]

Church Latin glosses it “dissimulation, pretense”.[6] British Medieval Latin keeps “pretence, deception”.[7] English simulation (mid-14th century), first “a false show”, comes from it, partly through Old French.[3]
