Tõusuni

Tõusuni is an Estonian grammatical form used to indicate a limit or boundary associated with a rise or increase. It is formed by attaching the suffix -ni to the genitive singular of a noun that denotes a rise or increase, producing phrases that mean “up to the rise” or “until the rise.” The construction is most common in technical or formal language, including economics, science, and public discourse.

Usage and meaning

Tõusuni expresses a temporal or quantitative boundary: something continues or is true up to the point of a rise. It is often found in phrases built around words such as hinnatõus (price increase) or temperatuuritõus (temperature rise). For example, hinnatõusuni võib jõuda tarbija ehk “the consumer may reach up to the price increase” or, more naturally in context, “On jäänud kaks nädalat hinnatõusuni” meaning “Two weeks remain until the price increase.” Similarly, temperatuuritõusuni kasutatavad andmed describe data up to the moment of a temperature rise.

Morphology

The form combines the root for the relevant rise concept with the genitive suffix and the -ni suffix. In practice, this yields compounds such as hinnatõusuni or temperatuuritõusuni. It is a productive derivational pattern in Estonian, extending the range of nouns that can express a boundary of change.

Relation to other forms

Tõusuni is related to other -ni suffix constructions in Estonian that denote limits or extents (for example, kõrguseni “up to the height,” ajani “until the time”). It is distinct in that it specifically revolves around a rise or increase as the limiting event.
