Ah, I see what you're getting at now. My apologies for the initial confusion. The correct word for "it" in plural form is simply "they." "They" functions as a third-person plural pronoun that can refer to a group of people or things.

For example, if we were discussing a group of cats, instead of saying "it," we would use "they." So, we might say: "Look at all those cats over there! They are so adorable."

I hope this answers your question more accurately. If you have any further inquiries or need assistance with anything else, please let me know!
