Relaxed walk south with giant (6)
I believe the answer is:
stroll
'relaxed walk' is the definition.
'stroll' can be an answer for 'walk' (stroll is a kind of walk). I'm unsure of the 'relaxed' bit.
'south with giant' is the wordplay.
'south' becomes 'S' (synonyms).
'with' means one lot of letters go next to another.
'giant' becomes 'troll' (I've seen this before).
's'+'troll'='STROLL'
Can you help me to learn more?
(Other definitions for stroll that I've seen before include "walk in a leisurely manner" , "Amble or ramble" , "A casual or lazy walk" , "Amble along" , "Meander" .)
