Root Explanation

Clinker originates from Middle English 'clinkere', which is derived from the verb 'clinken', meaning to make a ringing sound or to clink. The term refers to the hard, burnt residue left after coal has been burned, which can make a clinking sound when struck.

Memory Tip

Think of the sound 'clinking' that occurs when hard pieces of burnt material hit each other — that's why 'clinker' refers to the residue left after burning coal.
