Knocking to the wooden floor (7)
I believe the answer is:
decking
'knocking' is the definition.
The answer and definition can be both to do with contact as well as being present participle verbs.
Perhaps you can see a link between them that I can't see?
'the wooden floor' is the wordplay.
I cannot quite understand how this works, but
'floor' could be 'deck' (synonyms) and 'deck' is located in the answer.
This may be the basis of the clue (or it may be nonsense).
'to' is the link.
Can you help me to learn more?
(Other definitions for decking that I've seen before include "Garden platform" , "Wooden surface in garden" , "Material for timber platform" .)
