cleaver

The word 'cleaver' is a straightforward agent noun derived from the verb 'cleave'. The verb 'cleave' itself has a complex history, stemming from two distinct Old English verbs that merged in form but retained their opposite meanings: 'clēofan' (to split) and 'clifian' (to adhere). 'Cleaver' specifically draws from the 'to split' sense. The agent suffix '-er' was attached to indicate an instrument or person that performs the action of splitting. Thus, the literal logic is "a thing that splits," which perfectly describes the tool's primary function of dividing meat and bone. This formation follows a common Germanic pattern for creating tool names, similar to 'cutter' or 'grater'.

Structure: cleav (to split) + er (agent suffix) cleav (from Middle English 'cleven', Old English 'clēofan', meaning 'to split, adhere'; Germanic origin, related to 'cliff' and 'cleft'). er (agent-forming suffix, from Old English '-ere', of Germanic origin, indicating a person or thing that performs an action).
