Impale fruit for the last of the Mohicans (5)
I believe the answer is:
spear
'impale' is the definition.
(spearing is a kind of impaling)
'fruit for the last of the mohicans' is the wordplay.
'fruit' becomes 'pear' (pear is a kind of fruit).
'for' says to put letters next to each other (I've seen this in other clues).
'the last of' suggests the final letters.
The last letter of 'mohicans' is 's'.
'pear' put after 's' is 'SPEAR'.
(Other definitions for spear that I've seen before include "Shafted weapon for throwing or thrusting" , "Weapon to throw" , "Stabbing, throwing, weapon" , "Thrown weapon" , "asparagus for example" .)
