kitchen n.
"room in which food is cooked, part of a building fitted out for cooking," c. 1200, from Old English cycene "kitchen," from Proto-Germanic *kokina (source also of Middle Dutch cökene, Old High German chuhhina, German Küche, Danish kjøkken), probably borrowed from Vulgar Latin *cocina (source also of French cuisine, Spanish cocina), a variant of Latin coquina "kitchen," from fem. of coquinus "of cooks," from coquus "cook," from coquere "to cook" (from PIE root *pekw- "to cook, ripen").
The Old English word might be directly from Vulgar Latin.
