Conversation

I heard there’s a preclusion for attending the concert if you don’t have your ID.

Really? That seems a bit strict for just a concert.

Yeah, it might keep a lot of people from going, which is unfortunate.

Exactly! It’s like they’re making it harder to enjoy the event.

Root Explanation
Preclusion → It is formed from "pre-" (meaning before) and "claudere" (meaning to close). The word refers to the act of closing off or preventing something before it happens.
Memory Tip
Think of something being 'closed off' ('claudere') 'before' it can happen ('pre-') — that's why preclusion means preventing something in advance.
