Able to make an outburst (3)
I believe the answer is:
fit
I believe this clue is a double definition.
'able' is the first definition.
(similar in meaning)
'an outburst' is the second definition.
('fit' can be a synonym of 'outburst')
'to make' acts as a link.
(Other definitions for fit that I've seen before include "Be the right size or shape" , "Of a suitable standard" , "Adequate" , "In good shape; sudden attack" , "bout?" .)
