Madalatemperatuuril

Madalatemperatuuril is an Estonian phrase meaning "at low temperature." It is a compound formed from the adjective madal ("low"), the noun temperatuur ("temperature"), and the locative suffix -il, which marks a condition or location. The phrase functions as an adverbial expression, typically specifying the environmental or experimental conditions under which an action occurs.

The expression is commonly used in scientific and technical writing, but can appear in general prose when describing processes or phenomena that depend on temperature. Example: "Reaktsioon toimib madalatemperatuuril" ("The reaction proceeds at low temperature").

Estonian also forms comparable expressions for other temperature ranges, such as kõrgel temperatuuril ("at high temperature"). The term is not a standalone concept but a grammatical tool used to set conditions in sentences.

Etymology: madal + temperatuur + il; follows standard Estonian compounding rules and is used in the singular adessive form "madalatemperatuuril" to denote "at low temperature."
