Land not clayey? (5)
I believe the answer is:
light
I believe this clue is a double definition.
'land' is the first definition.
(light can mean to settle or land)
'not clayey?' is the second definition.
(soil might be described as light)
(Other definitions for light that I've seen before include "Not too demanding" , "skedaddle!" , "Portable" , "free gift from The Sun" , "Mild" .)
