Current medical changes enthusiastically welcomed (9)
I believe the answer is:
acclaimed
'enthusiastically welcomed' is the definition.
The answer and definition can be both to do with communicating as well as being past participle verbs.
Maybe you can see a link between them that I can't see?
'current medical changes' is the wordplay.
'current' becomes 'ac' (alternating current).
'changes' indicates anagramming the letters.
'medical' with letters rearranged gives 'claimed'.
'ac'+'claimed'='ACCLAIMED'
Can you help me to learn more?
(Other definitions for acclaimed that I've seen before include "Strongly praised" , "Hailed, heralded" , "Highly respected" .)
