Part of the body to nurse continually? (6)
I believe the answer is:
tendon
'part of the body' is the definition.
('tendon' is part of 'body')
'nurse continually?' is the wordplay.
'nurse' becomes 'tend' (I've seen this in another clue).
'continually?' becomes 'on' (I can't explain this - if you can you should give a lot more credence to this answer).
'tend'+'on'='TENDON'
'to' acts as a link.
Can you help me to learn more?
(Other definitions for tendon that I've seen before include "It's attaches tissue to bone" , "Tissue connecting a muscle with its bony attachment" , "Fibrous tissue attaching muscle to bone" , "Muscle attacher" , "Muscle-bone link" .)
