Old poet to drain broth (6)
I believe the answer is:
sappho
'old poet' is the definition.
(ancient Greek poet)
'drain broth' is the wordplay.
'drain' becomes 'sap' (sap can mean to suck or drain).
'broth' becomes 'pho' (I can't explain this - if you can you should believe this answer much more).
'sap'+'pho'='SAPPHO'
'to' is the link.
Can you help me to learn more?
(Other definitions for sappho that I've seen before include "Pa hops around the ancient Greek poetess" , "Pa hops about Greek poet from Lesbos" , "Greek lyric poet of Lesbos" , "Ancient Greek poet of Lesbos" , "Sixth century BC Greek poetess" .)
