Eccentric airman's maid? (6)
I believe the answer is:
marian
'maid?' is the definition.
The definition and answer are not the same part of speech.
'eccentric airman's' is the wordplay.
'eccentric' indicates an anagram.
'airman' with letters rearranged gives 'MARIAN'.
Can you help me to learn more?
(Other definitions for marian that I've seen before include "To do with Mary, mother of God" , "Robin Hood's maid" , "Holy woman" .)
