Steers clear of space in hollow asbestos (6)
I believe the answer is:
avoids
'steers clear of' is the definition.
(I've seen this before)
'space in hollow asbestos' is the wordplay.
'space' becomes 'void' (void is a kind of space**).
'in' is an insertion indicator.
'hollow' says to hollow out the word (remove centre letters).
'asbestos' with its middle taken out is 'as'.
'void' put inside 'as' is 'AVOIDS'.
(Other definitions for avoids that I've seen before include "Steers clear of, dodges" , "Escapes" , "Shuns, keeps away from" , "Stays away from" , "Ducks (out of)" .)
