Floor with gold and black polish (6)
I believe the answer is:
bedaub
'polish' is the definition.
The answer and definition can be both to do with contact as well as being verbs in their base form.
Perhaps there's an association between them I don't understand?
'floor with gold and black' is the wordplay.
'floor with' becomes 'bed' (I can't explain this - if you can you should believe this answer much more).
'gold' becomes 'Au' (Au is the chemical symbol for gold).
'and' means one lot of letters go next to another.
'black' becomes 'b' (as in pencil classifications).
'bed'+'au'+'b'='BEDAUB'
Can you help me to learn more?
(Other definitions for bedaub that I've seen before include "Smear (with a sticky substance)" , "Crudely paint" , "Smear with something sticky" , "Splodge with paint" .)
