An affair those compromised, somehow or another (5,1,7)
I believe the answer is:
after a fashion
'somehow or another' is the definition.
I can't tell whether this defines the answer.
'an affair those compromised' is the wordplay.
'compromised' is an anagram indicator (I've seen 'compromising' mean this (compromise can mean change)).
'an'+'affair'+'those'='anaffairthose'
'anaffairthose' with letters rearranged gives 'AFTER A FASHION'.
Can you help me to learn more?
(Other definitions for after a fashion that I've seen before include "Like a trendy shopper" , "contrive to be not that well" , "To a certain extent" , "Following a trend" , "Behind time" .)
