Looked tired or doped, possibly (7)
I believe the answer is:
drooped
'looked tired' is the definition.
I can't tell whether this definition defines the answer.
'or doped possibly' is the wordplay.
'possibly' indicates an anagram.
'or'+'doped'='ordoped'
'ordoped' is an anagram of 'DROOPED'.
Can you help me to learn more?
(Other definitions for drooped that I've seen before include "Sagged, wilted" , "Flagged" .)
