A certain approach from Orangemen with no ego (6)
I believe the answer is:
manner
'a certain approach' is the definition.
'manner' can be an answer for 'approach' (thesaurus). I'm not certain of the 'a certain' bit.
'from orangemen with no ego' is the wordplay.
'from' indicates an anagram (the anagram comes from the same letters).
'with no' suggests deleting specific letters.
'orangemen' with 'ego' taken out is 'ranmen'.
'ranmen' anagrammed gives 'MANNER'.
Can you help me to learn more?
(Other definitions for manner that I've seen before include "How something is said or done" , "Person's bearing or way of behaving" , "Kind, sort" , "Way in which something is done" , "Bearing; style of art" .)
