View affects space and time (6)
I believe the answer is:
aspect
'view' is the definition.
(synonyms)
'affects space and time' is the wordplay.
'affects' is an anagram indicator (I've seen 'affecting' mean this).
'and' is a charade indicator (letters next to each other).
'time' becomes 't' (abbreviation).
'space' with letters rearranged gives 'aspec'.
'aspec'+'t'='ASPECT'
(Other definitions for aspect that I've seen before include "Vista, panorama" , "View - distinct feature" , "Face" , "View - facial expression" , "Feature; appearance" .)
