litkovrilo

Read it right to left and it builds itself.Lito is a bed. Kovri is to cover. -Il- is the suffix for the instrument that does a thing, the same one in tranĉilo a knife, ŝlosilo a key, kombilo a comb. So lit-kovr-il-o is the tool for covering a bed. Three morphemes and a noun ending, and nobody needed a dictionary. The middle piece, kovrilo, is a perfectly good word on its own for any cover or lid - it is what goes on a pot as well as a bed - and this compound simply says which kind.

Watch kovri against kovi. One letter, and they sit only 2,400 ranks apart: kovri at 440 is to cover, kovi at 2,846 is to brood, to sit on eggs until they hatch. A hen kovas; a blanket kovras. Drop the r and your bedspread becomes an incubator. The pair is worth drilling now that both halves are in the course.

Which English word is it? Strictly a litkovrilo is the outer covering, the counterpane or bedspread that goes over everything. In practice speakers use it for a blanket as well, and if you want to be precise the thick woollen one is a lankovrilo, the one stuffed with feathers is a plumkovrilo, and the sheet underneath is a littuko. Nobody will misunderstand you either way, but the distinction exists.
