Poorly, ill (6)
I believe the answer is:
unwell
I believe this clue is a double definition.
'poorly' is the first definition.
(synonyms)
'ill' is the second definition.
(similar in meaning)
(Other definitions for unwell that I've seen before include "Off-colour" , "Quaintly amusing" , "Out of sorts" , "Somewhat ill" , "funny" .)
