Word History

Etymology

Noun

earlier, "person failing in a duty, offender," borrowed from Middle French delinquant, noun derivative from present participle of delinquer "to commit an offense," borrowed from Latin dēlinquere "to be lacking, fall short of an approved standard, misbehave, commit (an offense)" — more at delinquent entry 2

Adjective

borrowed from Latin dēlinquent-, dēlinquens, present participle of dēlinquere "to be lacking, fall short of an approved standard, misbehave, commit (an offense)," from dē- de- + linquō, linquere (perfect līquī) "to go away from, leave, leave behind, abandon, desist from," going back to Indo-European *li-n-k^w-/*li-né-k^w- "leaves behind" (whence also Sanskrit riṇákti "[s/he] leaves behind," Avestan irinaxti, Old Irish léicid "[s/he] lets go, leaves behind"), ar-léici "[s/he] lets go, releases, lends," present tense derivative from the base *lei̯k^w- "leave behind, distance oneself from," whence also, with varying ablaut, Greek leípō, leípein (aorist élipon) "to leave, quit, be missing," Armenian likʼ "(s/he) left, let go," Old Prussian polāikt "to remain," Lithuanian liekù, lìkti, Germanic *līhwan- "to grant, lend" (whence Old English lēon "to lend, grant," Old Saxon farlīhan, Old High German līhan, Old Norse ljá, Gothic leihwan "to lend")

Note: The specialization of sense in Germanic (from "leave behind" to "lend") is distinctive and has been variously explained. Attention has been drawn to the derivative *laihna- "something lent," perhaps from "something left as a legacy," with apparent counterparts in Indo-Iranian (see loan entry 1), and it has been argued that the noun's influence has restricted the meaning of the verb (see Antoine Meillet, "Sur le suffixe indo-européen *-nes-," Mémoires de la Société Linguistique de Paris, tome 15 [1908-09], pp. 254-56).
