She does flirt with one at centre (5)
I believe the answer is:
daily
'centre' is the definition.
Although both the answer and definition are singular nouns, I can't understand how they can define each other.
'she does flirt with one' is the wordplay.
I cannot quite see how this works, but
'one' could be 'i' (Roman numeral) and 'i' is found in the answer.
The remaining letters 'daly' is a valid word which might be clued in a way I don't see.
This may be the basis of the clue (or it may be nonsense).
'at' is the link.
Can you help me to learn more?
(Other definitions for daily that I've seen before include "Newspaper; cleaner" , "Every twenty-four hours" , "often" , "regularly" , "Cleaner; every 24 hours" .)
