Moved rapidly, like girl who ran with long, bounding stride (8)
I believe the answer is:
galloped
'moved rapidly like girl' is the definition.
The answer and definition can be both to do with motion as well as being past participle verbs.
Maybe you can see a link between them that I can't see?
'ran with long bounding stride' is the wordplay.
'ran' becomes 'loped' (loping is a kind of running).
'with' means one lot of letters go next to another.
'long bounding stride' becomes 'gal' (I can't justify this - if you can you should give a lot more credence to this answer).
'loped' put after 'gal' is 'GALLOPED'.
'who' acts as a link.
Can you help me to learn more?
(Other definitions for galloped that I've seen before include "'I - - , Dirck - - ...' (Browning)" , "Moved fast like a horse" , "Ran" , "Rode fast" , "A peg doll (anag.)" .)
