Bump into the daughter taking the dog out (7)
I believe the answer is:
collide
'bump into' is the definition.
(thesaurus)
'the daughter taking the dog out' is the wordplay.
'the daughter' becomes 'd'.
'taking the dog' becomes 'collie' (I can't justify this - if you can you should give a lot more credence to this answer).
'out' is an insertion indicator.
'd' put within 'collie' is 'COLLIDE'.
Can you help me to learn more?
(Other definitions for collide that I've seen before include "Smash together" , "Come into conflict" , "Hit" , "Crash together" , "Dash together; clash" .)
