Root Explanation

Excludability → It is formed from "ex-" (meaning out of or from) and "claudere" (meaning to close). The term refers to the ability to prevent someone from using a resource, thus closing it off from them.

Memory Tip

Think of 'closing off' ('claudere') something 'from' ('ex-') others — that's why excludability means the ability to keep others from using a resource.
