Scattered in all directions, hollow timber (6)
I believe the answer is:
strewn
'scattered' is the definition.
(I've seen this in another clue)
'in all directions hollow timber' is the wordplay.
'in' means one lot of letters goes inside another.
'all directions' becomes 'sewn' (compass directions).
'hollow' suggests removing the centre (the word is hollowed out).
'timber' with its centre removed is 'tr'.
'sewn' placed around 'tr' is 'STREWN'.
(Other definitions for strewn that I've seen before include "Scattered untidily" , "levelled in lines" , "Native of Brittany" , "Spread all over the place" , "Cast about" .)
