Derivational morphology often involves the addition of a derivational suffix or other affix. Such an affix usually applies to words of one lexical category (part of speech) and changes them into words of another such category. For example, one effect of the English derivational suffix -ly is to change an adjective into an adverb (slow → slowly).
Derivational morphemes, when combined with a root, change the semantic meaning or the part of speech of the affected word. For example, in the word happiness, the addition of the bound morpheme -ness to the root happy changes the word from an adjective (happy) to a noun (happiness).
In morpheme-based morphology, word forms are analyzed as arrangements of morphemes. A morpheme is defined as the minimal meaningful unit of a language. In a word such as independently, the morphemes are said to be in-, de-, pend, -ent, and -ly; pend is the (bound) root and the other morphemes are, in this case, derivational affixes.
Unlike derivational suffixes, English derivational prefixes typically do not change the lexical category of the base (and are so called class-maintaining prefixes). Thus, the word do, consisting of a single morpheme, is a verb, as is the word redo, which consists of the prefix re-and the base root do.
Affixes are bound by definition. [5] English language affixes are almost exclusively prefixes or suffixes: pre-in "precaution" and -ment in "shipment". Affixes may be inflectional, indicating how a certain word relates to other words in a larger phrase, or derivational, changing either the part of speech or the actual meaning of a word.
In a general non-theoretical sense polysynthetic languages are those languages that have a high degree of morphological synthesis, and which tend to form long complex words containing long strings of morphemes, including derivational and inflectional morphemes. A language then is "synthetic" or "synthesizing" if it tends to have more than one ...
The root morpheme is the primary lexical unit of a word, which carries the most significant aspects of semantic content and cannot be reduced to smaller constituents. [3] The derivational morphemes carry only derivational information. [4] The affix is composed of all inflectional morphemes, and carries only inflectional information. [5]
Inflection of the Scottish Gaelic lexeme for 'dog', which is cù for singular, chù for dual with the number dà ('two'), and coin for plural. In linguistic morphology, inflection (less commonly, inflexion) is a process of word formation [1] in which a word is modified to express different grammatical categories such as tense, case, voice, aspect, person, number, gender, mood, animacy, and ...
