How come "most" was used here? Is there any word, such as "with", skipped between the "most" and "interactions"?

"Most" in this case is an adjective used to describe the noun "interactions". So here, "most interactions" means "most" or the "majority" of the interactions. There is no word skipped between "most" and "interactions", since "most" is an adjective and "interactions" is a noun. Here's a few other examples of "most" used in this way: Ex: Most students at the school are from out of state. Ex: Most people want to be happy.
