Strongly recommends rises, but capital is lacking (5)
I believe the answer is:
urges
'strongly recommends' is the definition.
(I've seen this in another clue)
'rises but capital is lacking' is the wordplay.
'rises' becomes 'surges' (surging is a kind of rising).
'but capital is lacking' means to remove the first letter (capital letter of word).
'surges' with its initial letter removed is 'URGES'.
(Other definitions for urges that I've seen before include "Drives" , "Persuades to do something" , "Advocates strongly" , "Presses to do something" , "Strong impulses" .)
