Physicist gets back, carrying article for monarch (5,3,6)
I believe the answer is:
henry the second
'monarch' is the definition.
(I've seen this before)
'physicist gets back carrying article' is the wordplay.
I cannot quite see how this works, but
'physicist' could be 'henry' (Joseph Henry, 1797-1878) and 'henry' is present in the answer.
'back' could be 'second' (both can mean to support an idea or proposal) and 'second' is located in the answer.
'article' could be 'the' (the definite article in English) and 'the' is found in the answer.
This accounts for all the letters.
This explanation may well be incorrect...
'for' acts as a link.
Can you help me to learn more?
(Another definition for henry the second that I've seen is " king".)
