ttavaloppuisia

ttavaloppuisia is a hypothetical grammatical category used in linguistic discussions to illustrate how multiple affixes can encode temporality and plurality on a single word. The term combines two imagined suffixes: -ttava, which marks a prospective or impending state, and -loppuisia, which marks plurality and a bounded, end-related sense. In this construct, a single stem can bear both suffixes to produce a participial adjective with plural reference.

Origin and usage: The term is not attested in natural languages; it was coined for thought experiments and educational materials to explore morphotactics. It is often presented as a teaching device to show how affix stacking can create complex meanings and to discuss constraints on affix order and phonology.

Formation and semantics: In the proposed system, the base stem must be compatible with both suffixes. The typical order is stem + -ttava + -loppuisia. The resulting form functions as a modifier or predicative adjective referring to a plural set of imminent or near-end states. Phonology may adjust adjacent vowels or consonants when affixes attach, and some stems may require vowel alternations or consonant changes for ease of pronunciation.

Examples (illustrative, not canonical): run-ttava-loppuisia meaning "things that are about to run" (plural). read-ttava-loppuisia meaning "things that are about to be read" (plural). speak-ttava-loppuisia meaning "things that are about to be spoken" (plural).
