Moves lightly, like runners going round the park? (5)
I believe the answer is:
skips
'moves lightly' is the definition.
I can't judge whether this definition defines the answer.
'runners going round the park?' is the wordplay.
'runners' becomes 'skis' (ski is a kind of runner).
'going round' indicates putting letters inside.
'the park?' becomes 'p' (this might be a standard abbreviation which I don't know about).
'skis' placed around 'p' is 'SKIPS'.
'like' is the link.
Can you help me to learn more?
(Other definitions for skips that I've seen before include "Large containers for rubbish" , "Waste containers" .)
