Rostoucím

Rostoucím is a grammatical form in Czech, the instrumental singular of the present active participle rostoucí, derived from the verb růst (to grow). It functions as a modifier meaning “growing” or “increasing” and is used to describe something that is in the process of growth. The form is typically found in expressions where the instrumental case is required, such as when indicating rate, manner, or degree of growth.

Common usage occurs in formal and scientific contexts across fields such as economics, demographics, technology adoption, and social processes. Phrases using rostoucím describe ongoing development, for example rostoucím tempem (at a growing pace) or with rostoucím zájmem (with growing interest). The form can modify masculine, feminine, or neuter nouns in instrumental constructions, and it often appears with prepositions like s or ve to connect to the described phenomenon.

Examples:

- Ekonomika roste rostoucím tempem. (The economy is growing at a growing pace.)

- S rostoucím zájmem sledovali vývoj nové technologie. (They watched the development of the new technology with growing interest.)

- Populační růst pokračuje rostoucím tempem. (Population growth continues at a growing rate.)

Rostoucím is thus a compact way to express ongoing growth in Czech, widely used in descriptive, analytical, and explanatory writing to convey that something is actively increasing or developing.
