Self-restrained, yet consumed with anger? (9)
I believe the answer is:
temperate
'self-restrained' is the definition.
(I've seen this in another clue)
'consumed with anger?' is the wordplay.
'consumed' becomes 'ate' (to eat is to consume food).
'with' says to put letters next to each other.
'anger?' becomes 'temper' (temper is a kind of anger).
'ate' after 'temper' is 'TEMPERATE'.
'yet' is the link.
(Other definitions for temperate that I've seen before include "Showing moderation" , "comfortably warm?" , "Restrained" , "Abstemious" , "Continent" .)
