Derivational of bound morpheme

Morphemes are the smallest meaningful units of language. They are meaningful because they have either lexical or grammatical meaning. Morphemes can be classified into two namely free morphemes and bound morphemes. Free morphemes are those which can meaningfully stand alone while bound morphemes are the morphemes which cannot meaningfully stand alone. It means that bound morphemes must be attached to other morphemes. Bound morphemes are also called affixes which can be prefixes, infixes, or suffixes. Derivational morphemes are bound morphemes or affixes which derive (create) new words by either changing the meaning or the part of speech or both English only has prefixes and suffixes. Bound morphemes can be inflectional or derivational. In English, derivational morphemes can be prefixes and suffixes. In English, all prefixes are derivational but most of the prefixes in English do not change part of speech. Only several prefixes change the part of speech, on the other hand, most derivational English suffixes change part of speech. Only a small number of suffixes do not change part of speech
