Reliable or false story: truth about West (11)
I believe the answer is:
trustworthy
'reliable' is the definition.
('trustworthy' can be similar in meaning to 'reliable')
'false story truth about west' is the wordplay.
'false' is an anagram indicator.
'about' means one lot of letters goes inside another.
'west' becomes 'w' ('W' can be a synonym of 'west').
'story'+'truth'='storytruth'
'storytruth' is an anagram of 'trustorthy'.
'trustorthy' placed around 'w' is 'TRUSTWORTHY'.
'or' acts as a link.
(Other definitions for trustworthy that I've seen before include "Dependable" , "Honest; reliable" .)
