Well wrapped up, son walked with clumsy gait (8)
I believe the answer is:
swaddled
'well wrapped up' is the definition.
(I've seen this before)
'son walked with clumsy gait' is the wordplay.
'son' becomes 's' (genealogical abbreviation for son).
'walked' becomes 'waded' (wading is a kind of walking).
'with' is an insertion indicator.
'clumsy gait' becomes 'dl' (I can't explain this - if you can you should give a lot more credence to this answer).
'waded' enclosing 'dl' is 'waddled'.
's'+'waddled'='SWADDLED'
Can you help me to learn more?
(Other definitions for swaddled that I've seen before include "Wrapped in cloth" , "well wrapped up" , "Restricted by material" , "Tightly wrapped up" .)
