Explanation
A suffix is a bound morphological element that follows its base. It can participate in inflection or lexical word formation; its function follows from its use, not position alone. The boundary with the base requires morphological justification. A recurring sequence of letters at word endings is not automatically a suffix, and sound adjustments may complicate segmentation. Within the broader category of affixes, the term identifies a position without claiming that every language expresses the same categories through endings or that each suffix has only one meaning.
Movement of thought
1. Compare word forms. 2. Identify recurring final elements. 3. Determine the base. 4. Examine function. 5. Consider sound variants.
Scientific use case
Morphological analysis can compare suffix form, function and distribution.
Example
In German Kind-er (“children”), -er contributes to plural formation; in freund-lich (“friendly”), -lich forms an adjective.
Counterexample
The letters -er at the end of an arbitrary proper name do not by themselves constitute a plural suffix.
Distinction
Distinguish a suffix from a final syllable, letter sequence and exclusively derivational affix.
Effect on thought and perception
Suffixes reveal word structure following a base.
Resonance
A new grammatical relationship can begin at a word's end.
