One providing a walkover to settle game (10)
I believe the answer is:
footbridge
'one providing a walkover' is the definition.
Although both the answer and definition are singular nouns, I don't understand how one could define the other.
'settle game' is the wordplay.
'settle' becomes 'foot' (in the sense of footing a bill).
'game' becomes 'bridge' (card game).
'foot'+'bridge'='FOOTBRIDGE'
'to' acts as a link.
Can you help me to learn more?
(Other definitions for footbridge that I've seen before include "walkway" , "Pedestrian crossing, as it were" , "Over which one may walk" , "unsuitable for the motorist?" .)
