Etymology
The word 'bump' is a classic example of onomatopoeia, a word formed from the sound associated with its meaning. It first appeared in English in the mid-16th century, imitating the dull, hollow sound of a heavy impact. This imitative origin connects it to a family of similar-sounding words like 'thump' and 'clump,' all evoking a sense of heavy, blunt contact. Over time, its meaning expanded from the sound itself to describe the action of hitting, the instance of a collision, and the resulting physical swelling, all logically connected to the core concept of a blunt impact.
Analysis
The word 'bump' is a simplex word of imitative origin. It is not productively formed from smaller, meaningful morphemes in modern English.
