chaser

The word 'chaser' is a transparent English compound built from the verb 'chase' and the agentive suffix '-er'. The core verb 'chase' entered English from Old French, reflecting the Norman influence on the language of hunting and pursuit. Its ultimate Latin root, 'capere' (to seize), carries the fundamental idea of taking hold, which evolved into the concept of pursuing to catch. The suffix '-er' is a native English element used to form nouns denoting a person or thing performing an action, making 'chaser' literally 'one who chases'. This literal sense readily extended metaphorically to describe a drink that follows another or a tool that follows a form to finish it.

Structure: chase (to pursue) + er (agent suffix) 'chase' originates from Old French 'chacier', meaning 'to hunt, pursue', which itself came from Latin 'captiare', a frequentative of 'capere' (to take, seize). The suffix '-er' is from Old English '-ere', an agent noun suffix indicating 'one who does an action'.
