cwtch (a hiding place or cubby hole) is also from Welsh (albeit a recent word influenced by English, and used almost exclusively in the variant of English spoken in Wales, not in standard English), and crwth and cwtch are the longest English dictionary words without ⟨a, e, i, o, u, y⟩ according to Collins Dictionary.[9] A cwm[10] (pronounced /ˈkuːm/) is used in English in a technical geographical or mountaineering context to mean a deep hollow in a mountainous area, usually with steep edges on some sides, like a corrie or cirque, such as the Western Cwm of Mount Everest.
