tõhusas

Could you clarify what "tõhusas" refers to? Is it the Estonian word meaning “efficient” used in a specific grammatical form, or a proper noun such as a place, organization, or concept? With a bit more context I can write a concise, neutral wiki-style article (under 300 words) tailored to the intended meaning. If you’d like, I can also provide a general linguistics entry about the Estonian adjective “tõhus” and its related forms, or a stub for a fictional entity named Tõhusas.
