Released some profound ideas (5)
I believe the answer is:
undid
'released' is the definition.
(I've seen this before)
'some profound ideas' is the wordplay.
'some' indicates the answer is hidden within the clue (some of the parts of the word are used).
'UNDID' is hidden within 'profound ideas'.
(Other definitions for undid that I've seen before include "Released" , "Loosened; ruined" , "Unbuttoned" , "Disentangled" , "solved knotty problem" .)
