Forms

désireux (feminine désireuse, masculine plural désireux, feminine plural désireuses)[1] Old French desirrous, with the feminine desirruse in the Vie de saint Alexis.[1][2] A 13th-century text has desierrous.[3] The modern spelling désireux is recorded from the end of the 15th century.[4]

Etymology

It is formed from French désirer + -eux.[2][5][6] The Trésor compares the Late Latin adjective dēsīderōsus of the same meaning,[2] and Bloch and Wartburg and the GLLF allow that the French word may continue that Latin form directly.[7][4] désirer is from Latin dēsīderō (“to miss, long for”).[7]

Cognate with Old Occitan deziros, Catalan desitjós, Spanish deseoso, Portuguese desejoso and Italian desideroso.[3][7]

Earliest recorded meaning

It is first found about 1050 in the Vie de saint Alexis, in the line Ainz que t'vedisse, si'n fui mult desirruse “before I saw you, I longed for it greatly”.[3][2]

Semantic evolution

From the start the adjective had the active sense “who desires”, as it still has.[8][6] In the 16th century it was used with a noun complement, as in Amyot's desireux d'ouïr et d'apprendre and Montaigne's plus desireux de grande que de bonne reputation;[3] the Petit Robert labels désireux de with a noun (glory, honours, wealth) as old-fashioned, while désireux de with an infinitive, “wanting to, eager to”, is the modern use.[6] Used on its own, of a feeling or a look that shows desire, or as a noun (un désireux, la désireuse), it is rare and literary.[2]

English desirous (about 1300) comes from the Anglo-Norman and Old French adjective.[9]
