Arts subject, in brief, to include old Anglo-American poet (5)
I believe the answer is:
eliot
'poet' is the definition.
(TS Eliot)
I cannot understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for eliot that I've seen before include "Female novelist" , "Practical Cats author" , "T.S. or George?" , "T S . . . . . wrote ''The Waste Land''" , "thin material rejected" .)
