Dry prince hurt grasping king (7)
I believe the answer is:
parched
'dry' is the definition.
(similar in meaning)
'prince hurt grasping king' is the wordplay.
'prince' becomes 'p' (abbreviation for prince).
'hurt' becomes 'ached' (I've seen this in another clue).
'grasping' is an insertion indicator (inserted letters are held or grasped).
'king' becomes 'R' (abbreviation for rex, king in Latin).
'ached' enclosing 'r' is 'arched'.
'p'+'arched'='PARCHED'
(Other definitions for parched that I've seen before include "Extremely dry" , "Made dry and thirsty" , "Deprived of water" , "Dried out by heat" .)
