Forms

inconstant (feminine inconstante, masculine plural inconstants, feminine plural inconstantes)[1]

Etymology

It is borrowed from Latin inconstāns (“inconstant, inconsistent, changeable”), used of people and things.[2][3][4][5] The Latin word is formed from in- (“not”) and cōnstāns (“steady, consistent”),[3][6][7] the present participle of cōnstō (“to stand firm”), from com- and stō (“to stand”).[6] It is the opposite of constant, and inconstance was borrowed from inconstantia a little earlier, about 1220.[8]

Earliest recorded meaning

It is first found in Jean de Meun's part of the Roman de la Rose (1269–1278), meaning not steady in one's conduct.[2] The Grand Robert, the GLLF and the DHLF date it 1265.[3][6][8]

Semantic evolution

From not steady in conduct the adjective was applied about 1480 to a fickle lover.[2] From the 16th century it was also used of things, for what is liable to change, as in Ronsard (1550), and as a noun for an inconstant person (1560).[2][8] In the 16th century the word and inconstance became terms of love above all; the pairing of constancy and inconstancy, tied to the baroque and classical idea of love, has been old-fashioned since the 19th century, and the Petit Robert labels both main senses dated or literary.[8][9] Littré also records a natural-history sense, for zoological or botanical characters that are not fixed.[7] English inconstant (about 1400) came from the Old French word.[10]
