Walk slowly from valley, taking in edges of wood (6)
I believe the answer is:
Here is my best explanation:
'walk slowly' is the definition.
(I've seen this before)
'valley taking in edges of wood' is the subsidiary indication.
'valley' becomes 'dale' (dale is a kind of valley).
'taking in' is an insertion indicator.
'edges of' says to hollow out the word (remove centre letters).
'wood' with its centre taken out is 'wd'.
'dale' placed around 'wd' is 'dawdle'.
'from' is the link.
(Other definitions for dawdle that I've seen before include "'Linger, hang back (6)'", "Walk slowly and idly", "'Hang back, linger (6)'", "Drag one's feet", "Move slowly or idly", "Hang back, waste time", "Take your time, walk slowly", "Wander along slowly", "Loiter" and "Walk along idly, take your time".)
