big-bellied

the compound adjective "big-bellied" is a straightforward descriptive term formed within english. the first element, "big," originates from middle english, of uncertain origin, but has long carried the core sense of large size or importance. the second element, "bellied," derives from the noun "belly," which comes from old english "belg" meaning bag or pouch, a term that evolved to specifically denote the human abdomen. the suffix "-ed" is added to the noun to create an adjective, a common pattern in english for denoting possession of a characteristic. thus, the literal construction "having a large belly" transparently describes a physical state, often associated with corpulence or pregnancy.

Structure: big (large) + bellied (having a belly) big (old english, meaning large or great, used as an adjective); bellied (from middle english 'bely', meaning stomach or abdomen, combined with the suffix '-ed' to form an adjective meaning 'having a [specified kind of] belly')
