Walks around hospital to get what might be needed for stitches (7)
I believe the answer is:
threads
'might be needed for stitches' is the definition.
I can't judge whether this definition defines the answer.
'walks around hospital to get' is the wordplay.
'walks' becomes 'treads' (treading is a kind of walking).
'around hospital' becomes 'h' (abbreviation for hospital. I am not sure about the 'around' bit.).
'to get' means one lot of letters goes inside another.
'treads' enclosing 'h' is 'THREADS'.
'what' acts as a link.
Can you help me to learn more?
(Other definitions for threads that I've seen before include "Strands for sewing" , "Fine cords of twisted fibres" , "Strands of yarn" , "Thin fibres" , "Spiral ridges of screw or thin lengths" .)
