changeling

The word 'changeling' is a compound formed from the native English elements 'change' and the suffix '-ling'. The term emerged in the late 16th century, directly from the verb 'change', which itself has a journey from Late Latin cambiare (to exchange) via Old French. The suffix '-ling', of Germanic origin, denotes "one connected with a specific quality or action." The literal construction, "one who is changed or exchanged," perfectly captures the folklore narrative where a fairy child is exchanged for a human infant. This concrete, mythical meaning later broadened to describe any person or thing that has been substituted, demonstrating how a word formed for a specific supernatural belief evolved into a term for general substitution.

Structure: change (to alter) + ling (one belonging to) - change: From Old French changier, from Late Latin cambiare (to exchange, barter). Functions as the core verb root. - ling: From Old English -ling, a suffix forming nouns meaning "one belonging to or connected with." Functions as a diminutive or characteristic suffix.
