Quality of ladies very ordinary (3,8)
I believe the answer is:
bog standard
'ordinary' is the definition.
(I've seen this before)
'quality of ladies' is the wordplay.
I cannot really understand how this works, but
'quality' could be 'standard' (standard is a kind of quality) and 'standard' is located in the answer.
'of' could be 'o' and 'o' is present in the answer.
This may be the basis of the clue (or it may be nonsense).
'very' acts as a link.
Can you help me to learn more?
(Other definitions for bog standard that I've seen before include "Simple" , "Basic - ordinary (slang)" .)
