For example it's about to follow free range (5)
I believe the answer is:
ridge
'range' is the definition.
(I have seen 'Range of hills ' mean 'ridge' so perhaps 'range' could also mean 'ridge')
'for example it's about to follow free' is the wordplay.
'for example' becomes 'e.g.' (short for 'exempli gratia', 'for example' in Latin).
'it's about' says the letters should be written in reverse.
'to follow' is a charade indicator (letters next to each other) (some letters go after or follow others).
'free' becomes 'rid' (to be free of something is to be rid of it).
'eg' in reverse letter order is 'ge'.
'ge' put after 'rid' is 'RIDGE'.
(Other definitions for ridge that I've seen before include "Wrinkle" , "Narrow elevated strip" , "Long, narrow hilltop" , "Crest - spine" , "Hog's back" .)
