Avoid women after scheme losing millions in error (6)
I believe the answer is:
eschew
'avoid' is the definition.
(eschewing is a kind of avoiding)
'women after scheme losing millions in error' is the wordplay.
'women' becomes 'w'.
'after' means one lot of letters go next to another.
'losing' is a deletion indicator.
'millions' becomes 'm' (abbreviation).
'in error' is an anagram indicator.
'scheme' with 'm' taken away is 'schee'.
'schee' anagrammed gives 'esche'.
'w' after 'esche' is 'ESCHEW'.
(Other definitions for eschew that I've seen before include "'Avoid, keep away from (6)'" , "'Stay clear of, shun (6)'" , "Abstain from, shun" , "Deliberately stay away from" , "Avoid or abstain from, action or food" .)
