drapo

A specific cloth, not a general one. Drapo is broadcloth: heavy woollen fabric, milled and napped until the weave disappears, the stuff of overcoats, uniforms, billiard tables and the seats of old railway carriages. It is not the word for fabric in general. That is ŝtofo at rank 2,096, which covers any material you sew with, and if you are unsure which you want, ŝtofo is almost always the safer bet.

The fence with the verb, because English blurs it. In English, drape is mostly a verb - you drape a cloth over a chair - and the noun means a curtain. Esperanto keeps the two apart. Drapo is only ever the material. To drape, hang or arrange cloth in folds is drapiri, a separate root from French draper, and drapiraĵo is the drapery you end up with. So la drapo is what the tailor buys and la drapiraĵo is what the decorator hangs, and mixing them up is the single likeliest mistake an English speaker will make with this word.

Where it sits in the cloth vocabulary of this course.Lano at 2,543 is the wool itself, on the sheep or in the skein. Drapo is what wool becomes when it is woven and finished. Tolo, three ranks later in this same band, is the plain linen or canvas at the other end of the weight range - which is exactly the contrast the second example sentence is making. Silko is silk, veluro velvet, kotono cotton, and the tajloro at 2,752 turns any of them into a mantelo.

Why a nineteenth-century fabric ranks at all. Because the corpus is built from public-domain texts of 1887 to 1930, and in those books everybody is wearing a coat made of this. The frequency list is honest about where it comes from: some of what it teaches is the vocabulary of the world the language was born into.
