Relatively ironic radical makes a comeback accepting religious instruction (5)
I believe the answer is:
drier
'relatively ironic' is the definition.
I can't judge whether this definition defines the answer.
'radical makes a comeback accepting religious instruction' is the wordplay.
'radical' becomes 'red' (I've seen this in another clue).
'makes a comeback' says the letters should be written backwards (I've seen 'making a comeback' mean this).
'accepting' means one lot of letters goes inside another (inserted letters are accepted).
'religious instruction' becomes 'RI' (abbreviation).
'red' written backwards gives 'der'.
'der' placed around 'ri' is 'DRIER'.
Can you help me to learn more?
(Other definitions for drier that I've seen before include "More arid" , "Appliance to remove moisture" , "It removes moisture" , "See 1" , "Laundry machine" .)
