Also two points in the mountains (5)
I believe the answer is:
andes
'the mountains' is the definition.
(I've seen this in another clue)
'also two points in' is the wordplay.
'two points' means two substitutions for 'point'.
'also' becomes 'and' (both can mean in addition).
'point' becomes 's'.
'point' becomes 'e' (compass point).
'in' indicates putting letters inside.
'and'+'s'='ands'
'ands' going around 'e' is 'ANDES'.
(Other definitions for andes that I've seen before include "Mountains of 6 dn" , "Danes seen in mountains" , "Mountains for the Danes, oddly" , "Peak District" , "Danes in S American mountains" .)
