One who clinks, or a person who makes a clanking or clinking sound, especially someone who works with metal or chains.
From 'clink' (a sharp metallic sound) from Middle Dutch 'klinken' plus '-er' (agent noun). 'Clink' itself is likely onomatopoetic, imitating the sound it describes.
Medieval blacksmiths were the original clinker-ers—their workshops rang with the constant 'clink-clink-clink' that became the soundtrack of civilization building, and the word captures that auditory magic.
