Bring up commendation initially ignored (5)
I believe the answer is:
raise
'bring up' is the definition.
(I know that bring up can be written as raise)
'commendation initially ignored' is the wordplay.
'commendation' becomes 'praise' (praise is a kind of commendation).
'initially ignored' means to remove the first letter.
'praise' with its initial letter removed is 'RAISE'.
(Other definitions for raise that I've seen before include "Aries (anag)" , "cairn" , "Breed" , "Contact" , "climb" .)
