Inflectional suffixes

Inflectional Suffixes Characteristics

1) Express grammaticality or acquired features

2) Indicate relationships between different words in the sentence (e.g. in "Lee loves Kim," "s" marks third person singular and related to Lee)

3) Productive

4) Typically combine freely with all members of some large class of morphemes with predictable effects on usage and meaning (e.g. plural /s/ can be combined with any noun and have same effect on meaning)

5) Occur outside any derivational morphemes (are the last suffix)

6) In English, all inflectional morphemes are suffixes
