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' is a deletion indicator.
'content' means one lot of letters goes inside another.
'editor's' becomes 'seed' (I can't justify this - if you can you should give a lot more credence to this answer).
'rising' is a reversal indicator (letters written upwards in a down clue).
'ts' with 's' taken out is 't'.
't' going within 'seed' is 'seted'.
't'+'seted'='tseted'
'tseted' written backwards gives '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" .)
