Morphology

7-membered = 7-member (transparent) = 7 + member + ed

Formed from a numeral + 'member' (indicating number of members) with the adjectival suffix '-ed', so the meaning 'having seven members' is directly inferable.

Etymology

7-Membered simply means 'having seven members', where 7 is the number seven and membered comes from member, meaning 'a part of a group'. Imagine seven people holding hands in a circle, and a 7-membered ring in chemistry is the same idea but with seven atoms, which is why the term describes a ring of seven atoms.
