Fill suitcase with wolves (4)
I believe the answer is:
pack
This clue might be a double definition.
'fill suitcase' is the first definition.
'pack' can be an answer for 'fill' (packing is a kind of filling). I'm not sure about the 'suitcase' bit.
'wolves' is the second definition.
(pack of wolves)
'with' acts as a link.
Can you help me to learn more?
(Other definitions for pack that I've seen before include "Cardboard container" , "Put clothes etc into suitcase" , "Parcel" , "Prepare for holiday" , "Fill luggage - wolves" .)
