Claimed to be working with healthcare (7)
I believe the answer is:
medical
'healthcare' is the definition.
I can't tell whether this definition defines the answer.
'claimed to be working' is the wordplay.
'to be working' indicates anagramming the letters.
'claimed' is an anagram of 'MEDICAL'.
'with' acts as a link.
Can you help me to learn more?
(Other definitions for medical that I've seen before include "examination carried out by a doctor" , "Check-up - declaim (anag)" , "Relating to doctors" , "Health check-up" , "Declaim (anag) -- health check" .)
