They have a title for convenience (6)
I believe the answer is:
ladies
'for convenience' is the definition.
(I've seen this before)
I don't understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for ladies that I've seen before include "Lords' wives" , "...... and gentlemen" , "Females" , "Convenience" , "Women of rank in the British peerage" .)
