Take a winding course from home and err (7)
I believe the answer is:
meander
'take a winding course' is the definition.
(I've seen this before)
'from home and err' is the wordplay.
'from' says the answer is hidden in the clue.
'MEANDER' can be found hidden inside 'home and err'.
(Other definitions for meander that I've seen before include "Indirectly move" , "windy" , "Wander about, follow a winding course" , "Wind (like a river)" , "Wandering direction" .)
