Etymology
the word 'bulge' entered english in the 13th century from old french 'bouge', meaning a leather bag or wallet, which itself derived from latin 'bulga', a bag or knapsack of gaulish origin. the semantic shift from a 'bag' to a 'swelling' is a clear example of metonymy, where the characteristic shape of a filled bag became the primary meaning. this evolution illustrates how a concrete object's name can transform to describe a general, abstract shape or protrusion in the language.
Analysis
the word 'bulge' is a simplex word of old french origin. it cannot be meaningfully segmented into smaller, independent morphemes within modern english spelling.
