Points to them as subjects (6)
I believe the answer is:
themes
'subjects' is the definition.
('theme' can be a synonym of 'subject')
'points to them' is the wordplay.
'points' becomes 'Es' (two compass points).
'to' says to put letters next to each other (I've seen this in other clues).
'es' put after 'them' is 'THEMES'.
'as' is the link.
(Other definitions for themes that I've seen before include "Subjects or repeated melodies" , "Subjects or unifying ideas" , "items proposed for discussion" , "Motifs, subjects" , "Topics, ideas, motifs" .)
