aastapõhist

Aastapõhist is Estonian an adjective meaning year-based or annual, used to describe data, analyses, or events that are defined or organized by calendar year. It is commonly found in statistical, economic, and historical writing to indicate a temporal scope tied to a specific year.

The word is formed from the noun aasta (year) and the suffix -põhist, which yields adjectives indicating relation or basis. The base form is aastapõhine (annual), while aastapõhist appears in inflected forms such as partitive singular, for example in phrases like aastapõhist statistikat (annual statistics).

Usage and examples: In statistical texts one may see aastapõhist statistikat or aastapõhist teavet to denote information collected or reported on a yearly basis. In historical summaries, phrases such as aastapõhistest sündmustest may be used to refer to events that occurred within particular years. The form aastapõhist is the partitive singular used with nouns in contexts where the object is indefinite or not fully counted.

While aastapõhine describes something that is yearly, aastapõhist is the inflected form used in certain grammatical cases.
