Long-limbed and surprisingly angry (5)
I believe the answer is:
rangy
'long-limbed' is the definition.
(I've seen this in another clue)
'surprisingly angry' is the wordplay.
'surprisingly' is an anagram indicator (a surprising ordering of the letters).
'angry' with letters rearranged gives 'RANGY'.
'and' acts as a link.
(Other definitions for rangy that I've seen before include "with gangly limbs" , "Long-legged" , "Having long, slender limbs" , "Tall and thin" , "Tall, slim, long-limbed" .)
