Llyn

Llyn [ɬɨ̞n, ɬɪn] is the Welsh word for "lake" or, occasionally, "pond" or "pool". The word and its cognates in other Celtic languages (such as the Irish linn and the Breton lenn), as well their derivatives—including lyn, lynn and lin—appear in many placenames throughout the current and former Celtic world, as, for example, in Dublin and King's Lynn.
