Attaching a note with a tiny knot (5)
I believe the answer is:
tying
'attaching' is the definition.
The definition and answer can be both to do with contact as well as being present participle verbs.
Maybe they are linked in a way I don't understand?
'a note with a tiny knot' is the wordplay.
'a note' becomes 'g' (musical note).
'with' means one lot of letters go next to another.
'knot' indicates an anagram (I've seen 'knotted' mean this).
'tiny' anagrammed gives 'tyin'.
'g' after 'tyin' is 'TYING'.
Can you help me to learn more?
(Other definitions for tying that I've seen before include "Scoring the same" , "Linking" , "Restricting" , "Binding, fastening" , "restrictive" .)
