Mähiste

Could you clarify what "mähiste" refers to? The term does not correspond to a clearly defined topic in widely used sources without additional context. Please specify the language (for example Estonian, German, or another), and the intended domain (a place name, a person or surname, a concept in biology or culture, a historical term, etc.). Once I know the exact meaning or context, I can draft a concise, neutral wiki-style article (under 300 words) in plain text.
