Words related to room

cove (n.1)

early 14c., "den, cave, gollow nook," from Old English cofa "small chamber, cell," from Proto-Germanic *kubon (compare Old High German kubisi "tent, hut," German Koben "pigsty," Old Norse kofi "hut, shed").

Extension of meaning to "small bay, inlet, or creek" is from 1580s, apparently via Scottish dialectal meaning "small hollow place in coastal rocks" (a survival of an Old English secondary sense). Also in early Middle English, "chamber, closet, pantry," hence the legal phrase cove and keie "right of the mistress of a household to control 'pantry and key,'" that is, to manage the household (late 13c.).

-th (2)
suffix forming nouns of action, state, or quality from verbs or adjectives (such as depth, strength, truth), from Old English -ðu, , from Proto-Germanic *-itho (cognates: Old Norse , Old High German -ida, Gothic -iþa), abstract noun suffix, from PIE *-ita (cognates: Sanskrit -tati-; Greek -tet-; Latin -tati-, as in libertatem "liberty" from liber "free"). Sometimes in English reduced to -t, especially after -h- (as in height).
