Etymology

From Middle English barnakille, from earlier bernake, bernekke, from Old Northern French bernaque (“barnacle”) (compare French barnache), from Medieval Latin barneca (“limpet”), from Gaulish (compare Welsh brennig, Irish báirneac), from Proto-Celtic *barin?kos, from *barin? (“rock, rocky ground”) (compare Old Irish barenn (“boulder”)), from Proto-Indo-European *g?r?H- (“hill, mountain”) + Proto-Celtic *-?kos, from Proto-Indo-European *-kos, *-?os; for sense development, compare Ancient Greek ????? (lépas, “rock”) which gave ????? (lepás, “limpet”).
