Frank pictures from the East in spectators' range (8)
I believe the answer is:
straight
'frank' is the definition.
(I've seen this before)
'pictures from the east in spectators' range' is the wordplay.
'pictures' becomes 'art'.
'from the east' is a reversal indicator (on a map from right to left).
'in' is an insertion indicator.
'spectators' range' becomes 'sight' (I have seen 'Range of vision ' mean 'sight' so perhaps 'range' could also mean 'sight'. I am not sure about the 'spectators'' bit.).
'art' in reverse letter order is 'tra'.
'tra' put within 'sight' is 'STRAIGHT'.
Can you help me to learn more?
(Other definitions for straight that I've seen before include "Respectable" , "Poker hand of 5 consecutive cards" , "not gay" , "Instantly - honest" , "Not curved or bent" .)
