indecēns (genitive indecentis); third-declension one-termination adjective[1]
Etymology
It is from Latin in- (“not”) + decēns (“seemly, becoming”),[2][3] decēns being the present participle of decet (“it is fitting”).[4] That verb goes back to Proto-Italic *dek-ē- (“fits, is right”) and Proto-Indo-European *deḱ-eh₁-.[5]
Earliest recorded meaning
Its first citation in the OLD is from Vitruvius (c. 84–c. 25 BC), meaning unseemly or unfitting.[2][6]
Semantic evolution
In the 1st century AD it also meant unsightly or unattractive: Seneca writes of a swelling belly not hidden “as if an unseemly burden” (quasi indecens onus).[2] Petronius has a character ask numquid indecens sum? (“am I ugly?”); Martial uses it of a nose, Suetonius of laughter and Quintilian of delays.[7]
Medieval Latin used it for what is unbecoming or shameful, ill-suited or unworthy, and in law for what is not allowed.[8] In Britain it described, for example, a mitre of unsightly form in an inventory of 1414.[9] English indecent (1560s), “unbecoming, in bad taste”, comes from French indécent or directly from Latin.[4]
