püsivamast
Püsivamast is a term that may appear in informal Estonian discussions to convey a sense of being more permanent or lasting than something else. It is not a standard entry in major Estonian dictionaries and is not recognized as an official inflected form in standard grammar. In most contexts, writers prefer using the standard comparative püsivam or, for emphasis, phrases such as püsivam kui or the superlative form used in context.
Etymology and status: the form seems to be derived from the adjective püsiv (meaning permanent or lasting)
Usage and interpretation: when püsivamast appears, readers should treat it as nonstandard and rely on the ordinary
Alternatives: the conventional way to express comparison is püsivam; for the highest degree of permanence, use
