Pledge company millions will go to university (6)
I believe the answer is:
commit
'pledge' is the definition.
(I've seen this in another clue)
'company millions will go to university' is the wordplay.
'company' becomes 'comm' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'millions' becomes 'm' (abbreviation).
'will go' indicates named letters should be taken away.
'to university' becomes 'MIT' (Massachusetts Institute of Technology).
'mit' with 'm' taken away is 'it'.
'comm'+'it'='COMMIT'
Can you help me to learn more?
(Other definitions for commit that I've seen before include "Send for trial" , "Entrust; perpetrate" , "Perpetrate - promise - put away" , "Entrust; pledge (oneself)" , "Perpetrate, carry out (a crime)" .)
