Questions & Answers about Выступающий приоткрыл окно в аудитории.
Why does Выступающий end like an adjective but act as a noun in this sentence?
Выступающий is a substantivized participle. It is originally the present active participle of the verb выступать (to speak publicly / to perform), literally meaning 'the one who is speaking'. In this sentence, it functions entirely as a noun meaning 'the speaker', taking the subject position.
If выступающий acts as a noun, how does it decline if we change its role in the sentence?
Even though it functions as a noun, it still follows standard adjective declension rules. For example, if you wanted to say 'I listened to the speaker', it would take the dative case just like an adjective: Я слушал выступающего.
What does the prefix при- add to the verb открыл in приоткрыл?
The prefix при- often indicates an incomplete, partial, or slight action. While открыл simply means 'opened', приоткрыл specifically means 'opened slightly' or 'cracked open'.
I've seen аудитория used to mean 'audience' (the people). Does it mean the same thing here?
Context is key. Аудитория can mean 'audience' (the listeners), but it also commonly means 'auditorium', 'lecture hall', or 'university classroom'. Because of the preposition в (in) and the physical action of opening a window, it clearly refers to the room itself in this sentence.
