Giant making some progress (4)
I believe the answer is:
ogre
'giant' is the definition.
(I've seen this before)
'some progress' is the wordplay.
'some' indicates the answer is hidden within the clue (some of the parts of the word are used).
'OGRE' can be found hidden inside 'progress'.
'making' acts as a link.
(Other definitions for ogre that I've seen before include "Bugbear" , "Monstrous creature" , "Wicked and inhuman person" , "Fairy tale giant" , "Monstrous person" .)
