As we know, when the pronoun someone is used, the succeeding verb will be conjugated in the 3rd-person singular. Thus, the following sentence demonstrates legal usage:

I cannot enter the room; someone is cooking.

However, note the following sentence:

I cannot enter the room; someone is cooking, are they not?

As can be seen in the second sentence, when a question tag is used, it doesn't use the corresponding conjugation of the 3rd-person singular previously used, but rather, it takes on the 3rd-person plural. Why is this the case? What is more, why is the following sentence illegal?

I cannot enter the room; someone are cooking, are they not?

I thank you, in advance, for your responses.

"Someone" (as well as "anyone", "everyone", "no-one") takes the singular form (example source). This is why

I cannot enter the room; someone is cooking

is correct but

I cannot enter the room; someone are cooking

is not.

However, "someone" is gender-neutral, and so when that "someone" is referred to by a personal pronoun, "they" (taking the plural form) is used instead of "he" or "she", because "they" is the most commonly used gender-neutral pronoun - see here.
