Word before or after "first" (6)
I believe the answer is:
ladies
'word before or after first' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for ladies that I've seen before include "Public facility" , "Convenience" , "Ideals for genteel women" , "...... and gentlemen" , "Women, of refinement perhaps" .)
