Thousands of words are obviously associated with numbers, for example, a monologue is a speech by 1 person; a bicycle has 2 wheels; a tripod is a stool with 3 legs; a quadruped is an animal with 4 legs; a pentathlon consists of 5 athletic events; a sextet is a piece for 6 musicians; a heptagon is a 7-comered figure; an octopus has 8 "feet"; a nonagenarian has lived for 9 decades; and decimal means counting in lOs; but in many other cases the connections, once just as vivid, etymology of "number": from Indo-European root meaning "share" or "portion" and seems to have been originally associated with the division of land_ "Nimble" refers to one who is quick to take his share; your "nemesis" was originally your portion of Fate. German: nehmen, to take, [Meaning "symbol or figure of arithmatic value" is from c.1391. ] number words often show strange combinations. e.g. 18 in Welsh: is deunaw; = twice 9 (naw). 50 is half-hundred.
