「〜かもしれない」 expresses the speaker’s educated guess or assumption about a situation. The level of probability implied is generally considered to be 50% or less.

「〜かどうか」 is straightforward, but it adheres strictly to the rule of connecting with the Plain Form (普通形, futsūkei) of the preceding word.

[Noun related to Sensation] + が + する is used to describe an involuntary perception—something that registers in your senses without you trying to make it happen.

[疑問詞]〜か is used to embed a specific piece of unknown information into a larger statement or another question. In English, this is known as an indirect question.

〜終わる (owaru) is attached to the end of another verb to indicate that the action has been completed. In Japanese, we "glue" the word for "finish" (終わる) directly onto the action.

'〜間に' (aida ni) means "while," "during," or "in the midst of." It signifies that an action or state occurs within a certain period of time.

The grammar "間 (aida)" functions as a noun, you simply need to connect it to other words as if you were describing a noun like "book" or "house."

The grammar point 〜てみる is formed by taking the て-form of a verb and attaching みる (miru). While みる typically means "to see" or "to look," when combined in this structure, it takes on a different, more nuanced meaning.
