Have you ever had to deal with billable hours at work?

Yeah, it's a bit stressful trying to keep track of everything.

Root Explanation
Billable → It is formed from "bill" (from Old French *bille*, meaning a written account or invoice) and "-able" (meaning capable of). The word "billable" refers to something that is capable of being billed or charged for services rendered.
Memory Tip
Think of a 'bill' as a written account of charges, and '-able' means capable. So, something that is billable is capable of being charged on a bill.
