The workers used a rammer to compact the soil before laying the foundation.
Rammer → The word 'rammer' is derived from the verb 'ram' (from Old English 'ramman', meaning to strike or push) combined with the suffix '-er' (meaning a person or thing that performs an action). A rammer is thus a device or person that strikes or pushes something forcefully.
Think of someone or something that 'strikes' ('ram') to remember that a 'rammer' is a tool or person that pushes or forces something.
