In modern Finnish, it is not recognized as a common word, and reliable sources directly defining määräis are scarce. Because of its rarity, the form is often encountered only in dialectal, historical, or typographical contexts, where it may be a nonstandard spelling or a mistaken form of related words such as määräinen or määrätä.
