Praise former road charge? Not entirely! (5)
I believe the answer is:
extol
'praise' is the definition.
(extolling is a kind of praising)
'former road charge? not entirely' is the wordplay.
'former' becomes 'ex' (prefix meaning former or onetime).
'road charge?' becomes 'toll' (I've seen this before).
'not entirely' means to remove the last letter (most but not all of the word).
'toll' with its final letter removed is 'tol'.
'ex'+'tol'='EXTOL'
(Other definitions for extol that I've seen before include "Exalt" , "Warmly approve of" , "Speak highly" , "Acclaim" , "'Praise, glorify (5)'" .)
