The root is the primary
lexical unit of a
word, which carries the most significant aspects of
semantic content and cannot be reduced into smaller constituents.
Content words in nearly all
languages contain, and may consist only of, root
morphemes. However, sometimes the term "root" is also used to describe the word minus its
inflectional endings, but with its lexical endings in place. For example, chatters has the inflectional root or
lemma chatter, but the lexical root chat. Inflectional roots are often called
stems, and a root in the stricter sense may be thought of as a monomorphemic stem.
