I heard you got a new bicycle; does it have an accumulator?

Yeah, it actually helps with the battery and lights.

Root Explanation

Accumulator → It is formed from "ad-" (meaning to) and "cumulare" (meaning to heap or pile up). The word describes something that gathers or piles up over time, such as energy or data.

Memory Tip

Think of something that 'piles up' ('cumulare') as it 'adds to' ('ad-') a collection — that's what an accumulator does.
