Folkloric giant (5)
I believe the answer is:
troll
'folkloric giant' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for troll that I've seen before include "Creature from Norse mythology" , "who's stirring on-line" , "Try to catch fish" , "Scandinavian monster" , "Draw baited line, to lure fish" .)
