Sight, for example, various points (5)
I believe the answer is:
sense
'sight for example' is the definition.
(sighting is a kind of sensing)
'various points' is the wordplay.
'various' becomes 'sen' (I am not sure about this - if you are sure you should believe this answer much more).
'points' becomes 'se'.
'sen'+'se'='SENSE'
Can you help me to learn more?
(Other definitions for sense that I've seen before include "Perceive; meaning" , "Feel, perceive" , "Smell, say" , "Sound practical judgment" , "Tenor" .)
