taper

taper: [OE] Taper is ultimately the same word as paper. Both go bach to Latin papyrus ‘papyrus’. This was used among other things for a ‘candlewick made from papyrus’, and hence for a ‘candle’. It seems to have been borrowed in this sense into Old English as *papur, and by a process known as dissimilation (in which one of a pair of similar speech sounds is changed, so as to break up the pair) it became tapur. The verb taper ‘become narrower’, which emerged in the 16th century, is an allusion to the shape of the candle.
=> paper, papyrus

taper (n.)

Old English tapur, taper "candle, lamp-wick," not found outside English, possibly a dissimilated borrowing from Latin papyrus (see papyrus), which was used in Medieval Latin and some Romance languages for "wick of a candle" (such as Italian papijo "wick"), because these often were made from the pith of papyrus. Compare also German kerze "candle," from Old High German charza, from Latin charta, from Greek khartes "papyrus, roll made from papyrus, wick made from pith of papyrus."

taper (v.)

1580s, "shoot up like a flame or spire," via an obsolete adjective taper, from taper (n.), on the notion of the converging form of the flame of a candle. Sense of "become slender, gradually grow less in size, force, etc." first recorded c. 1600. Transitive sense from 1670s. Related: Tapered; tapering.
