Noted about new connection (6)
I believe the answer is:
'connection' is the definition.
Although both the answer and definition are singular nouns, I don't understand how they can define each other.
'noted about new' is the wordplay.
'about' indicates an anagram.
'new' becomes 'n' (common abbreviation eg NT for New Testament).
'noted' with letters rearranged gives 'tendo'.
Can you help me to learn more?
(Other definitions for tendon that I've seen before include "Muscle attacher" , "In words" , "horse's hamstring" , "Strong cord of bodily tissue" , "It's attaches tissue to bone" .)
