End-pieces for cues! (4)
I believe the answer is:
tips
'cues' is the definition.
The definition and answer can be both related to thinking as well as being plural nouns.
Maybe there's an association between them I don't understand?
'end-pieces' is the wordplay.
'end' becomes 'tip' (tip is a kind of end).
'pieces' becomes 's' (I can't explain this - if you can you should give a lot more credence to this answer).
'tip'+'s'='TIPS'
'for' is the link.
Can you help me to learn more?
(Other definitions for tips that I've seen before include "Turns over" , "extra payments" , "leavings in restaurant?" , "Gratuties" , "Ends" .)
