Georgian city dull -- it'll probably get wet underfoot (4,3)
I believe the answer is:
bath mat
'it'll probably get wet underfoot' is the definition.
I can't tell whether this defines the answer.
'georgian city dull' is the wordplay.
'georgian city' becomes 'bath' (I've seen this before).
'dull' becomes 'mat' (mat as opposed to glossy).
'bath'+'mat'='BATH-MAT'
Can you help me to learn more?
(Other definitions for bath mat that I've seen before include "One may stand on it wet" , "Rug alongside washing facility" , "It keeps moisture off the floor" , "One may be floored" , "It takes wet feet" .)
