Root Explanation

The word 'bolthead' is formed from 'bolt' (from Old English 'bolt', meaning a type of fastener) and 'head' (from Old English 'heafod', meaning the upper part of the body or a leader). A bolthead refers to the head or top part of a bolt, which is the part that is often visible and serves as the fastening mechanism.

Memory Tip

Think of a 'bolt' as a fastener and 'head' as the top part — together, they form the 'bolthead', which is the top part of a bolt.
