Etimoloji [ "pre-p&-zi-sh&n ] (noun.) 14th century. From Latin praepositio, from praeponere (to place before); prae (before) + ponere (to put, place); compare French préposition. (See position, and compare provost.) So called because it is usually placed before the word with which it is phrased, as in a bridge of iron, he comes from town, it is good for food, he escaped by running.
