Määrin is a word in Estonian that is linked to the verb määrama, meaning to determine or set, and to the related noun määr, meaning a limit or boundary. In contemporary Estonian, määrin occurs mainly in formal, technical, or historical texts rather than in everyday speech.

The term functions as an adverbial element or a conjunction-like marker that introduces a condition or a basis for a statement. In English, its sense is often approximated by phrases such as “provided that,” “in accordance with,” or “to the extent that,” depending on the context. Because its use is restricted to specific registers, määrin tends to appear in fixed phrases or in legal and administrative language rather than in casual prose.

Määrin is considered part of a broader word family around määr- and määrama, which encode ideas of determination, limitation, and regulation. Its presence can signal formality or archival character, and in many modern texts it may be replaced by more common constructions such as kui (if), vastavalt (in accordance with), or lugedes (according to), depending on the precision required by the sentence.

Overall, määrin is a relatively specialized Estonian term whose primary role is to mark conditionality or basis within formal or official language. Its usage illustrates how Estonian often relies on nuanced adverbial or connective elements to convey conditions and specifications in a precise legal or technical sense.
