Feverish, so slept with pyjama bottoms only? (7)
I believe the answer is:
topless
'feverish' is the definition.
Both the definition and answer are adjectives. Perhaps you can see an association between them that I can't see?
'so slept with pyjama bottoms only?' is the wordplay.
'so slept' anagrams to 'TOPLESS'.
But, I am not clear how the anagram is indicated.
Can you help me to learn more?
(Other definitions for topless that I've seen before include "Without a shirt, vest or bra?" , "Half-naked" , "Wearing no clothing above the waist" , "Bare-breasted" , "Leaving the breasts uncovered" .)
