Ready to go walkies when you tempt into trouble (4,2)
I believe the answer is:
lead on
'walkies when you tempt into trouble' is the definition.
I can't judge whether this defines the answer.
'ready to go' is the wordplay.
'ready' becomes 'on' (if a device is on it is ready for use).
'to' means one lot of letters go next to another (I've seen this in other clues).
'go' becomes 'lead' (synonyms).
'on' after 'lead' is 'LEAD ON'.
Can you help me to learn more?
(Other definitions for lead on that I've seen before include "Deceive in fun" , "Tempt, encourage" , "Take for a ride" , "Show the way inside" , "Persuade to do something foolish; trick, deceive" .)
