I get in trouble but make light of the matter (6)
I believe the answer is:
ignite
'but make light of the matter' is the definition.
I can't judge whether this definition defines the answer.
'i get in trouble' is the wordplay.
'trouble' indicates an anagram.
'get'+'in'='getin'
'getin' anagrammed gives 'gnite'.
'i'+'gnite'='IGNITE'
Can you help me to learn more?
(Other definitions for ignite that I've seen before include "Cause to start burning" , "Kindle Fire" , "Spark off" , "Swan constellation" , "'Set alight, fire up (6)'" .)
