Muutlikud

Muutlikud is the plural nominative form of the Estonian adjective muutlik, which means changeable or variable. The word is used to describe things that are not constant and may vary under different conditions. It is common in scientific, technical, and everyday language to refer to multiple factors, properties, or conditions that can change, such as changes in environment, outcomes, or parameters.

Etymology and grammar: The adjective muutlik is formed from the verb muutma, “to change,” with the derivational suffix -lik, producing the sense “changeable.” Like other Estonian adjectives, muutlik agrees with the noun in number and case; in the plural nominative the form is muutlikud. The related noun muutlikkus denotes the state or quality of variability.
