the inner resources of a language are used in a variety of ways. Compounding is process of putting two or more existing words together to form new words. these words are called compound words such as 'greenhouse', 'bellhop', 'classroom',and 'red tape'. sometimes a complex word rather than a compound word results when a derivational affix is added to stem on which it has not been previously used, as in 'emplane', 'stardom'. 'sexy', 'hospitalize' and 'inflattionary'
