Recalled perfect tense for "break out" (5)
I believe the answer is:
erupt
'break out' is the definition.
('erupt' can be a synonym of 'break out')
'recalled perfect tense' is the wordplay.
'recalled' says the letters should be written backwards.
'perfect' becomes 'pure' ('pure' can be a synonym of 'perfect').
'tense' becomes 't' (abbreviation used in many dictionaries).
'pure' reversed gives 'erup'.
'erup'+'t'='ERUPT'
'for' is the link.
(Other definitions for erupt that I've seen before include "Suddenly appear" , "Break out dramatically" , "Eject lava" , "Emit lava" , "Break out suddenly and violently" .)
