Considerable distance on the golf course? (7)
I believe the answer is:
fairway
'golf course?' is the definition.
(I've seen this before)
'considerable distance on' is the wordplay.
'considerable' becomes 'fair' (I've seen this before).
'distance' becomes 'way' (way is a kind of distance).
'on' says to put letters next to each other.
'fair'+'way'='FAIRWAY'
'the' acts as a link.
(Other definitions for fairway that I've seen before include "Golf course area between tee and green" , "Part of golf course between tee and green" .)
