suffixti

Suffixti is a term used in linguistic typology to describe a class of suffixal morphemes that attach to the end of a word and convey grammatical information. The name combines the general idea of a suffix with the notion of a recurring suffixal shape, often illustrated in discussions by reference to a hypothetical or representative suffix called -ti. In this sense, suffixti functions as a label for a family of related morphemes rather than a single, specific affix.

Classification and function

Suffixti are typically described as occurring in languages with rich suffixation, including many agglutinative and polysynthetic systems. They can be inflectional, contributing to tense, aspect, mood, number, case, or evidentiality, or derivational, creating new lexical items or changing word class. The same language may employ multiple suffixti that stack on a single stem, forming complex word forms.

Phonology and morphology

Patterns among suffixti vary across languages. Some exhibit predictable allomorphy or align with phonological processes such as vowel harmony or final-consonant adjustments. Others show irregular or morphophonemic alternations. The exact behavior of a given suffixti is therefore language-specific, influencing how stems combine with affixes and how surface forms are realized.

Distribution and usage

The term suffixti is not universally adopted and appears mainly in descriptive or exploratory discussions, including work on constructed languages and on understudied natural languages. Because it denotes a class rather than a fixed set of morphemes, its boundaries depend on scholarly usage and the particular language being described.
