Cot
mid 17th century (originally Anglo-Indian, denoting a light bedstead): from Hindi khāṭ ‘bedstead, hammock’.
wiktionary
Borrowed from Hindi खाट(khāṭ), from Sauraseni Prakrit 𑀔𑀝𑁆𑀝𑀸(khaṭṭā), from Sanskrit खट्वा(khaṭvā, “bedstead”).
From Middle English cot, cote, from Old English cot and cote(“cot, cottage”), from Proto-Germanic *kutą, *kutǭ (compare Old Norse kot, Middle High German kūz(“execution pit”)), from Scythian (compare Avestan 𐬐𐬀𐬙𐬀 (kata, “chamber”)). Cognate to Dutch kot(“student room; small homestead”). Doublet of cote; more distantly related to cottage.
From Irish cot, coit(“small boat”), from Proto-Celtic *quontio, from Proto-Indo-European *póntoh₁s(“path, road”), related to Gaulish and Latin ponto. Compare the first element of catboat, which could be a borrowing. [1]
From dialectal cot, cote, partly from Middle English cot(“matted wool”), from Old English *cot, *cotta, from Proto-Germanic *kuttô(“woolen fabric, wool covering”); and partly from Middle English cot, cote(“tunic, coat”), from Old French cote, from the same Germanic source (see English coat). Possibly influenced by English cotton.
