Structural types of words

· simple words: single root morphemes, e.g. agree, child, red, etc.

Root word has only a root morpheme in its structure. This type is widely represented by a great number of words belonging to the original English stock or to earlier borrowings: e.g. house, room, book, work, port.

In Modern English, it has been greatly enlarged by the type of wordbuilding called conversion: to hand, v. formed from the noun hand; can, v. from can, n.; to pale, v. from pale, adj.; a find, n. from to find, v.

· derivatives: affixational derived words consisting of one or more affixes: e.g. enjoyable, childhood, unbelievable. Derived words are extremely numerous in the English vocabulary.

· compound words. Compound words consist of two or more stems 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.

· compound derivatives. Derivational compounds are words in which components are joined together by means of compounding and affixation: e.g. ovalshaped, strong-willed.

· phrasal verbs: to put up with; to give up; to take for.
