Naming terms for mother superiors to circle the globe (5)
I believe the answer is:
nouns
'naming terms' is the definition.
'nouns' can be an answer for 'terms' (I've seen this before). I'm not certain of the 'naming' bit.
I can't explain the rest of the clue.
Can you help me to learn more?
(Other definitions for nouns that I've seen before include "Words that can be the subject or object of a verb" , "Words referring to people, places or things" , "They refer to people, places and things" , "Words referring to person, place or thing" , "terms" .)
