            Word Formation II
            1.Affixation
            Affixation is the process of forming words by adding derivational affixes to stems. It is also called derivation. Words formed in this way are derivatives.
            1) Prefixation
            Prefixation is a way of forming new words by adding prefixes to stems. Usually, prefixes do not change the part of speech of a word. Their chief function is to modify its meaning, although there are exceptions. Prefixes can be divided, based on their meanings, into: negative prefixes, reversative prefixes, pejorative prefixes, prefixes of degree or size, locative prefixes, prefixes of time and order, number prefixes and miscelaneous prefixes.
            2)Suffixation
            Suffixation is the process of forming new words by adding suffixes to the end of stems. The chief role of a suffix is not to modify the meaning of a stem, rather to change the grammatical function of a stem, though there are a few exceptions. Suffixes can be divided into noun suffixes, adjective suffixes, adverb suffixes and verb suffixes.
            2.Compounding
            1) Definition
            Compounding is a process of word formation by which two or more stems are put together to make one word. The word formed in this way is called a compound
            2) Characteristics of compounds
            (1)Phonetic feature
            The word stress of a compound usually falls on the first element, while in a free phrase, the second element is usually stressed. If a compound has two stresses, it is the first element that receives the primary stress.
            (2)Semantic feature
            The meaning of a compound is a semantic unity, which,usually, is not the total sum of all the meanings of the constituent words in a compound.
            (3) Grammatical feature
            A compound usually plays a single grammatical role in a sentence.
