Questions & Answers about В первом сезоне наша команда играла в другой лиге.
Why do we say в первом сезоне instead of в первый сезон?
Because it answers the question 'when?' regarding a specific phase or stage. For periods like a season, century, or month, Russian uses the preposition в plus the Prepositional case. Since сезон (season) is masculine, the ordinal number первый takes the masculine Prepositional ending -ом, becoming первом.
What case is в другой лиге, and why does другой end in -ой here?
This is also the Prepositional case, used to show location (where they played). The noun лига (league) is feminine, so it changes to лиге. The word другой (other/another) might look like a masculine dictionary form here, but -ой is actually the standard feminine Prepositional ending for this word.
Could другой mean 'one more' league in this context?
No, другой means 'another' strictly in the sense of 'a different one'. If the team were playing in an additional league at the same time, you would use ещё одной лиге. Here, they switched to a completely different league.
Since a team is made up of many people, why is the verb играла in the singular feminine form?
