Haughty; projecting (5)
I believe the answer is:
proud
I believe this clue is a double definition.
'haughty' is the first definition.
(similar in meaning)
'projecting' is the second definition.
(I've seen this before)
(Other definitions for proud that I've seen before include "Feeling gratified or arrogant" , "Walking tall" , "Guilty of deadly sin" , "Haughty; projecting a little" , "With high self-opinion" .)
