For instance, in English, the abstract noun beauty (already a fused form with an incorporated suffix) may mean 'pleasing quality'.
Adding the causative verbal suffix -fy (a functional morpheme) produces the verb beautify 'to make pleasing'.
By adding the suffix -ful (another functional morpheme), the adjective beautiful is formed.
Some languages, such as Kharia,[1] can be analyzed as having a single major word class composed of semantic bases or content morphemes.
Thus, the distinction between nouns, verbs, and adjectives in such languages is entirely morphological (realized through the concatenation of functional morphemes), rather than lexical (having separate entries in the lexicon for each of the major word classes).
