Small child in danger on icy street (4)
I believe the answer is:
skid
'danger on icy street' is the definition.
The definition and answer can be both acts as well as being singular nouns.
Perhaps there's an association between them I don't understand?
'small child' is the wordplay.
'small' becomes 's' (abbreviation - e.g. clothes size).
'child' becomes 'kid' (synonyms).
's'+'kid'='SKID'
'in' is the link.
Can you help me to learn more?
(Other definitions for skid that I've seen before include "Of vehicle, slide as on ice" , "Swerve out of control" , "go out of control" , "Uncontrolled slide" , "Slip, slide" .)
