Long article about Astyanax’s origin, Greek in Homer (7)
I believe the answer is:
achaean
'greek in homer' is the definition.
'achaean' can be an answer for 'greek' (Achaean is an example). I am not certain of the 'in homer' bit.
'long article about astyanax's origin' is the wordplay.
'long' becomes 'ache' (to long for something is to ache for it).
'article' becomes 'an' (indefinite article).
'about' is an insertion indicator.
'origin' suggests taking the first letters.
The initial letter of 'astyanaxs' is 'a'.
'ache'+'an'='achean'
'achean' enclosing 'a' is 'ACHAEAN'.
Can you help me to learn more?
(Other definitions for achaean that I've seen before include "Ancient Greek" , "provincial Greek" , "about ancient Greeks" .)
