Is it suitable for high tea? (5,4)
I believe the answer is:
tipsy cake
'is it suitable' is the definition.
I can't tell whether this defines the answer.
'high tea?' is the wordplay.
'high' becomes 'tipsy' (I've seen this in another clue).
'tea?' becomes 'cake' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'tipsy'+'cake'='TIPSY-CAKE'
'for' acts as a link.
Can you help me to learn more?
(Other definitions for tipsy cake that I've seen before include "Dessert of sponge soaked with wine or spirits" , "Trifle with alcohol, almonds and crystallised fruit" , "Pudding" , "sweet" , "Trifle with white wine or sherry" .)
