Did you see that obstruction in the road earlier?

Yeah, it really slowed down traffic!

I hope they clear it soon, or it'll be a mess.

For sure, no one wants to deal with that kind of delay.

Root Explanation

Obstruction is formed from "ob-" (meaning against) and "struere" (meaning to build). The word describes something that builds against or blocks a path or progress.

Memory Tip

Think of something that is 'against' ('ob-') what is 'built' ('struere') — that's why obstruction means something that blocks or hinders.
