Did you know that I had to rebore the holes for the new shelves?

Really? I didn't think that was necessary.

Root Explanation

Rebore → It is formed from "re-" (meaning again) and "bore" (from Old English "borian", meaning to pierce or drill). The word "rebore" means to bore or drill again.

Memory Tip

Think of doing something 'again' ('re-') that involves 'piercing' or 'drilling' ('bore') — that's why rebore means to bore again.
