Finger, for example, like it (5)
I believe the answer is:
digit
'finger for example' is the definition.
(finger is a kind of digit)
'like it' is the wordplay.
'like' becomes 'dig' (I've seen this in another clue).
'dig'+'it'='DIGIT'
(Other definitions for digit that I've seen before include "one's given?" , "Single number" , "zero, one, two, three, four, five, six, seven, eight, or nine" , "Single figure - finger" , "Single numeral" .)
