Recurrent cold - I intend acting sickly (7)
I believe the answer is:
anaemic
'sickly' is the definition.
Both the answer and definition are adjectives. Maybe you can see a link between them that I can't see?
'recurrent cold i intend acting' is the wordplay.
'recurrent' says the letters should be written backwards (recurrent can mean turning back).
'cold' becomes 'C' (eg on taps).
'intend' becomes 'mean' (synonyms).
'acting' becomes 'a' (abbreviation, eg in job titles).
'c'+'i'+'mean'+'a'='cimeana'
'cimeana' written backwards gives 'ANAEMIC'.
Can you help me to learn more?
(Other definitions for anaemic that I've seen before include "Lacking in red corpuscles" , "Suffering from lack of red corpuscles in blood" , "bloody poor" , "Pale and weak, lacking vigour" , "uninspiring" .)
