Dodge an empty space (5)
I believe the answer is:
avoid
'dodge' is the definition.
(I know that dodge can be written as avoid)
'an empty space' is the wordplay.
'an' becomes 'a'.
'empty space' becomes 'void' (I've seen this in another clue).
'a'+'void'='AVOID'
(Other definitions for avoid that I've seen before include "Stay away from or circumvent" , "Keep away from (someone/something)" , "Get out of" , "Stay clear of" , "Eschew" .)
