isestiisesti

isestiisesti is a hypothetical linguistic concept used in discussions of Finnic-inspired constructed languages. It refers to a process of extreme adverbial intensification achieved by applying the adverbial suffix -isesti in a layered or reduplicated form. The term is not attested in natural languages and is mainly found in conlang literature and experimental syntax discussions as a tool for exploring how adverbial derivation can interact with degree modification.

Origins and usage: The coinage combines the familiar Finnish adverbial suffix -isesti with reduplication or layering, producing adverbs with a meaning that exceeds the ordinary -isesti form. In theoretical descriptions, it is treated as a separate morpho-syntactic category that yields a stronger or more emphatic degree sense than standard adverbs formed with -isesti.

Grammar and phonology: In the described framework, -isestiisti (the intensified form) attaches to adjectives or participial stems and typically occupies the same syntactic positions as ordinary adverbs. Phonological adaptations may occur when the suffix is repeated, with stress reallocation favoring the root and occasional vowel adjustments to preserve rhythm.

Examples: Standard: kauniisti (beautifully). Intensified hypothetical form: kauniistiesti (extremely beautifully). Another example: nopeasti (quickly) versus nopeastiesti (extremely quickly). In running text, such forms would be marked as non-canonical or experimental.

Reception: As a fictional construct, istiesti is used mainly for pedagogical demonstrations and for exploring the limits of adverbial morphology in Finnic-inspired conlangs. It serves as a thought experiment rather than a documented feature of natural languages.
