He, tall, enraged and deadly (6)
I believe the answer is:
lethal
'deadly' is the definition.
(I know this)
'he tall enraged' is the wordplay.
'enraged' indicates an anagram.
'he'+'tall'='hetall'
'hetall' anagrammed gives 'LETHAL'.
'and' is the link.
(Other definitions for lethal that I've seen before include "bringing about the end?" , "Deadly, potentially fatal" , "bringing down the curtain" , "describing a killer?" , "Liable to cause death" .)
