Questions & Answers about На этой поляне летом много комаров, поэтому мы не сидим там долго.
Russian usually uses на with open spaces, surfaces, and many outdoor locations, while в is more common for enclosed spaces.
So:
- на поляне = in/on the clearing
- в комнате = in the room
A поляна is an open clearing, so на sounds natural.
Also, after на in a location meaning, Russian uses the prepositional case:
- эта поляна → на этой поляне
So на этой поляне means on/in this clearing.
Because the phrase is in the prepositional case, singular, feminine.
The base form is:
- эта поляна = this clearing
After на meaning location, both the adjective/pronoun and the noun must match in the prepositional case:
- эта → этой
- поляна → поляне
So:
- на этой поляне = in this clearing / on this clearing
This is normal adjective-noun agreement in Russian.
