It raised northeast spike (4)
I believe the answer is:
tine
'spike' is the definition.
(spike of a fork)
'it raised northeast' is the wordplay.
'raised' is a reversal indicator (going up in a down clue).
'northeast' becomes 'NE' (abbreviation).
'it' back-to-front is 'ti'.
'ti'+'ne'='TINE'
(Other definitions for tine that I've seen before include "Slender prong of fork" , "Spike" , "(Fork's) prong" .)
