widely represented by a great number of words belonging to the original English stock or to earlier borrowings (house, room, book, work, port, street, table, etc.), and, in Modern English, has been greatly enlarged by the type of word-building called conversion (e. g. to hand, v. formed from the noun hand; to can, v. from can, п.; to pale, v. from pale, adj.; a find, n. from to find, v.; etc.).
Another wide-spread word-structure is a compound word consisting of two or more stems1 (e. g. dining-room, bluebell, mother-in-law, good-for-nothing). Words of this structural type are produced by the word-building process called composition.
The somewhat odd-looking words like flu, pram, lab, M. P., V-day, H-bomb are called shortenings, contractions or curtailed words and are produced by the way of word-building called shortening (contraction).
The four types (root words, derived words, compounds, shortenings) represent the main structural types of Modern English words, and conversion, derivation and composition the most productive ways of word-building.
To return to the question posed by the title of this chapter, of how words are made, let us try and get a more detailed picture of each of the major types of Modern English word-building and, also, of some minor types.
The process of affixation consists in coining a new word by adding an affix or several affixes to some root morpheme. The role of the affix in this procedure is very important and therefore it is necessary to consider certain facts about the main types of affixes.
1 Stem is part of the word consisting of root and affix. In English words stern and root often coincide.
