Retired woman concealing worry about written work (5)
I believe the answer is:
iliad
'written work' is the definition.
'iliad' can be an answer for 'work' (I've seen this before). I'm not certain of the 'written' bit.
'retired woman concealing worry' is the wordplay.
'retired' says the letters should be written in reverse.
'woman' becomes 'di' (short for Diana).
'concealing' indicates putting letters inside.
'worry' becomes 'ail' (I've seen this in another clue).
'di' going around 'ail' is 'daili'.
'daili' back-to-front is 'ILIAD'.
'about' acts as a link.
Can you help me to learn more?
(Other definitions for iliad that I've seen before include "epic work" , "story of Mediterranean heroism" , "Homer Trojan war epic" , "Epic piece of writing" , "heroic work" .)
