This document discusses morphology and morphemes. It defines morphology as the study of word formation and structure. Morphemes are defined as the smallest units of meaning in a language. There are two types of morphemes: lexical morphemes which have meaning on their own (like words), and grammatical morphemes which specify relationships between lexical morphemes (like suffixes). Morphemes can also be free, meaning they can stand alone as words, or bound, meaning they only occur combined with other morphemes. The document provides examples and further discusses types of morphemes and processes of word formation.
