Praise former road charge? Not entirely! (5)
I believe the answer is:
extol
'praise' is the definition.
(I know that extol is a more specific form of the action praise)
'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 taken off 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)'" .)
