T S Eliot ignoring content editor's rising hate (6)
I believe the answer is:
detest
'hate' is the definition.
(to detest is to hate or loathe)
't s eliot ignoring content editor's rising' is the wordplay.
'eliot' becomes 'ts' (poet TS Eliot).
'ignoring' indicates named letters should be taken away.
'content' means one lot of letters goes inside another.
'editor's' becomes 'seed' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'rising' says the letters should be written backwards (going up in a down clue).
'ts' with 's' taken out is 't'.
't' going into 'seed' is 'seted'.
't'+'seted'='tseted'
'tseted' back-to-front is 'DETEST'.
Can you help me to learn more?
(Other definitions for detest that I've seen before include "Loathe, hate intensely" , "Dislike intensely, loathe" , "Find repulsive" , "Be unable to stand" , "Having a loathing" .)
