Eccentric airman's maid? (6)

I believe the answer is:

marian

I'm a little stuck... Click here to teach me more about this clue!

'maid?' is the definition.
The answer and definition are not the same part of speech.

'eccentric airman's' is the wordplay.
'eccentric' indicates anagramming the letters.
'airman' anagrammed 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" .)

I've seen this clue in the Evening Standard.
