Tloppuisia

Tloppuisia is a term used in some linguistic discussions to refer to a class of terminal, or end-marking, suffixes found in certain word-formation systems. The term is a compound imagined from the Finnish root loppu meaning end and the adjectival suffix -isia, applied in scholarly contexts to label endings that indicate finality or termination in morphology. In analyses, tloppuisia endings are described as attaching after a sequence of other affixes and giving the word a conclusive or completing interpretation within the clause or noun phrase.

Tloppuisia is typically discussed in relation to agglutinative or polysynthetic languages, where multiple morphemes attach to a stem. Such endings may encode features like termination status, aspectual completion, or final mood, and they can interact with agreement and stem alternations. The term is often used in discussions of constructed languages or theoretical grammars to illustrate how a terminal affix could function independently from other morphemes.

In practice, published examples are usually synthetic or illustrating rather than reporting attested natural-language data. A basic illustration might present a stem S followed by a sequence of affixes F1 and F2, with the tloppuisia ending T added last to signal terminal meaning: S + F1 + F2 + T. The concept serves as a tool for exploring how end-marking morphology could operate within a language’s overall affix system.
