Rants when one breaks deals (7)
I believe the answer is:
tirades
'rants' is the definition.
(I've seen this before)
'when one breaks deals' is the wordplay.
'when one' becomes 'i' (Roman numeral. I am not sure about the 'when' bit.).
'breaks' indicates putting letters inside.
'deals' becomes 'trades' ('trade' can be a synonym of 'deal').
'i' put within 'trades' is 'TIRADES'.
Can you help me to learn more?
(Other definitions for tirades that I've seen before include "torrents of abuse" , "Long angry speeches of criticism or accusation" , "Speeches of violent denunciation" , "Rants" , "It dares to unleash long angry speeches" .)
