Make dishevelled airmen tea - that will restore their spirits (9)
I believe the answer is:
reanimate
'make' is the definition.
The definition and answer can be both related to bodily activities as well as being verbs in their base form.
Perhaps you can see an association between them that I don't see?
'dishevelled airmen tea that will restore their spirits' is the wordplay.
'airmen tea' can be anagrammed to 'REANIMATE'.
Though, I am not sure how the anagram is indicated.
Can you help me to learn more?
(Other definitions for reanimate that I've seen before include "put new life in him!" , "Get excited again" .)
