Catchphrase from southern Irish singer (6)
I believe the answer is:
slogan
'catchphrase' is the definition.
(eg a political catchphrase)
'southern irish singer' is the wordplay.
I cannot really see how this works, but
'southern' could be 's' (abbreviation) and 's' is located in the answer.
The remaining letters 'logan' 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).
'from' acts as a link.
Can you help me to learn more?
(Other definitions for slogan that I've seen before include "Word or phrase adopted as motto" , "Tag line" , "Battle cry - advertising phrase" , "Motto, catchy phrase" , "Rallying cry" .)
