Misguidedly, we ate hurt red hen. Feeling sick! (5,3,7)
I believe the answer is:
under the weather
'feeling sick' is the definition.
'under the weather' can be an answer for 'sick' (I've seen this in another clue). I'm not certain of the 'feeling' bit.
'misguidedly we ate hurt red hen' is the wordplay.
'misguidedly' indicates an anagram.
'we'+'ate'+'hurt'+'red'+'hen'='weatehurtredhen'
'weatehurtredhen' anagrammed gives 'UNDER THE WEATHER'.
Can you help me to learn more?
(Other definitions for under the weather that I've seen before include "put umbrellas up here?" , "Indisposed" , "Depressed" , "Seedy" , "the worse for wear" .)
