Looked intensely happy to be out and about (6)
I believe the answer is:
glared
'looked intensely' is the definition.
The answer and definition can be both related to bodily activities as well as being past participle verbs.
Perhaps there's an association between them I don't understand?
'happy to be out and about' is the wordplay.
'happy' becomes 'glad' (similar in meaning).
'to be out' means to remove the last letter.
'and' is a charade indicator (letters next to each other).
'about' becomes 'red' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'glad' with its final letter removed is 'gla'.
'gla'+'red'='GLARED'
Can you help me to learn more?
(Other definitions for glared that I've seen before include "Lowered" , "Glowered" , "Looked angrily" , "Stared fiercely" , "Was too bright" .)
