Time perfect to return and blow top (5)
I believe the answer is:
erupt
'blow top' is the definition.
'erupt' can be an answer for 'blow' (I've seen this in another clue). I am not sure about the 'top' bit.
'time perfect to return' is the wordplay.
'time' becomes 't' (abbreviation).
'perfect' becomes 'pure' (synonyms).
'to return' says the letters should be written in reverse.
't'+'pure'='tpure'
'tpure' back-to-front is 'ERUPT'.
'and' is the link.
Can you help me to learn more?
(Other definitions for erupt that I've seen before include "Discharge" , "be active" , "suddenly burst out" , "What canines do" , "spout" .)
