Arrive with empty lorry? That's fair (6)
I believe the answer is:
comely
'fair' is the definition.
(I know that fair can be written as comely)
'arrive with empty lorry?' is the wordplay.
'arrive' becomes 'come' (synonyms).
'with' means one lot of letters go next to another.
'empty' suggests removing the centre.
'lorry' with its middle taken out is 'ly'.
'come'+'ly'='COMELY'
'that's' acts as a link.
(Other definitions for comely that I've seen before include "Very pleasing to the eye, as Dev's maidens perhaps" , "Quite good-looking" , "Archaic word for good-looking, say maidens" , "Fair (but not lovely!)" , "Old word for good-looking, say a lass" .)
