Seeing drunk grabbing queen, charge! (8)
I believe the answer is:
energise
'charge' is the definition.
('charge'->'energize' is in my internal thesaurus and 'ize'->'ise')
'seeing drunk grabbing queen' is the wordplay.
'drunk' is an anagram indicator.
'grabbing' indicates putting letters inside.
'queen' becomes 'ER' (short for Elizabeth Regina ie Queen Elizabeth).
'seeing' anagrammed gives 'engise'.
'engise' going around 'er' is 'ENERGISE'.
(Other definitions for energise that I've seen before include "Give power to" , "Give vitality to" , "Activate" , "Stimulate activity" , "Motivate" .)
