Borrowed from Welsh edling, from Middle Welsh edling, edlyg, from Old English eþeling, Mercian form of æþeling, possibly through an intermediate Middle English *edelyng. Doublet of atheling. The modern pronunciation with /d/ is either a spelling pronunciation (in Middle Welsh, represented /ð/) or represents the development of earlier /ðl/ into /dl/ in Middle English.
