diaper-changing

The compound 'diaper-changing' is a modern formation that combines two words with distinct historical lineages. 'Diaper' originates from a term for a rich, patterned cloth, its meaning narrowing over centuries to specifically denote the linen or fabric used for infants, and finally to the disposable absorbent garment itself. 'Changing' derives from a Latin verb meaning to swap or exchange one thing for another. When combined, the literal sense of "exchanging the cloth garment" perfectly captures the practical, routine action the term describes, evolving from its components' concrete meanings into a standard lexical item for a specific caregiving task.
