ttaessapäätteestä

ttaessapäätteestä is a term that occasionally appears in Finnish linguistic discussions, but it is not part of standard Finnish grammar. It does not have a fixed definition in core reference works and is used only in niche or theoretical contexts to discuss morphological interfaces in word formation. Because it is not widely recognized, readers should treat it as a speculative label rather than a canonical term.

Etymology and conceptually related ideas: the expression combines ttaessa, the present participle/converb form used to indicate simultaneous action (for example, kirjoittaessa “while writing”), with päätteestä, the elative form of päätteet meaning “suffixes” or “endings.” As a coined label, it is intended to point to a boundary where a derivational participle suffix attaches to a stem and an inflectional ending is added. In this sense, ttaessapäätteestä is used to discuss the interface between derivational morphology and inflectional endings rather than to describe a standalone word form.

Usage and cautions: because the term is not standardized, it appears mainly in theoretical prose or in demonstrations that aim to illustrate affixal boundaries. Many grammars and textbooks describe the same phenomena more directly, using phrases like “a participial form followed by an inflectional ending” instead of employing a coined label. When encountered, the term should be interpreted in its specific context and not assumed to have a universal definition across sources.

Example (hypothetical): a writer might imagine a sequence in which a verb stem receives the participial suffix -ttaessa and then an ending -stä is appended; the juncture between these affixes could be discussed using the label ttaessapäätteestä.
