<Li> Function morphemes can be free morphemes that are prepositions, pronouns, determiners, and conjunctions . Additionally, they can be bound morphemes that are inflectional affixes . </Li> <P> Roots are composed of only one morpheme, while stems can be composed of more than one morpheme . Any additional affixes are considered morphemes . An example of this is the word quirkiness . The root is quirk, but the stem is quirky which has two morphemes . Moreover, there exist pairs of affixes that have the same phonological form, but have different meaning . For example, the suffix--er can be derivative (e.g. sell ⇒ seller) or inflectional (e.g. small ⇒ smaller). These types of morphemes are called homophonous . </P> <P> Some words might seem to be composed of multiple morphemes, but in fact they are not . This is why one has to consider form and meaning when identifying morphemes . For example, the word relate might seem to be composed of two morphemes, re - (prefix) and the word late, but this is not correct . These morphemes have no relationship with the definitions relevant to the word like "feel sympathy", "narrate", or "being connected by blood or marriage". Furthermore, the length of the words does not determine if it has multiple morphemes or not . To demonstrate, the word Madagascar is long and it might seem to have morphemes like mad, gas, and car, but it does not . Conversely, small words can have multiple morphemes (e.g. dogs). </P> <Table> <Tr> <Td> </Td> <Td> This section needs additional citations for verification .
