It’s a sort of tea-break and you eat too much (7)
I believe the answer is:
satiate
'eat too much' is the definition.
'satiate' can be an answer for 'eat' (satiating is a kind of eating). I am not certain of the 'too much' bit.
'it's a sort of tea-break and you' is the wordplay.
'sort of' indicates anagramming the letters.
'break' indicates anagramming the letters.
'and' means one lot of letters go next to another.
'you' becomes 'i' (I am not sure about this - if you are sure you should believe this answer much more).
'ts'+'a'='tsa'
'tsa' anagrammed gives 'sat'.
'tea' is an anagram of 'ate'.
'ate' after 'i' is 'iate'.
'sat'+'iate'='SATIATE'
Can you help me to learn more?
(Other definitions for satiate that I've seen before include "Overfill - gorge" , "Fill to satisfaction" , "Gratify fully" , "Completely satisfy" , "stuff" .)
