Ted's out for a kiss, but is made to pay! (5)
I believe the answer is:
taxed
'is made to pay' is the definition.
I can't tell whether this definition defines the answer.
'ted's out for a kiss' is the wordplay.
'out' indicates putting letters inside.
'for' becomes 'a' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'a kiss' becomes 'x' (X can represent a kiss).
'a'+'x'='ax'
'ted' enclosing 'ax' is 'TAXED'.
'but' is the link.
Can you help me to learn more?
(Other definitions for taxed that I've seen before include "Weighed down" , "Was demanding" , "Heavily burdened" , "Stretched" , "Made heavy demands on" .)
