linguo-, lingu-, lingua-, -linguist, -linguistic, -linguistical, -linguistically +

(Latin: literally tongue; and by extension, speech, language)

From Old Latin dingua which is a cognate (kindred) with Old English tunge, The change of d (in Old Latin dingua) to l (in Latin lingua) was probably due to dialectal influence (the so-called "Sabine l"). It was facilitated by a folk-etymological association with lingere, "to lick", the tongue having been conceived as "the licking organ".
