A way to hold a scarf on (6)
I believe the answer is:
aboard
'on' is the definition.
Both the answer and definition are adverbs. Perhaps they are linked in a way I don't understand?
'a way to hold a scarf' is the wordplay.
'way' becomes 'rd' (short for road).
'to hold' is an insertion indicator.
'a scarf' becomes 'boa' (boa is a kind of scarf).
'a'+'rd'='ard'
'ard' enclosing 'boa' is 'ABOARD'.
Can you help me to learn more?
(Other definitions for aboard that I've seen before include "Ready to sail" , "on a plane, perhaps" , "on base" , "at sea, say?" , "... [CRUISE SHIP] here, perhaps" .)
