Make a smashing entrance (9)
I believe the answer is:
gatecrash
This could be a double definition.
'make' is the first definition.
The answer and definition can be both to do with motion as well as being verbs in their base form.
Maybe you can see an association between them that I don't see?
'a smashing entrance' is the second definition.
Although both the answer and definition are verbs in their base form, I can't see how they can define each other.
Can you help me to learn more?
(Other definitions for gatecrash that I've seen before include "Try to get in for free" , "enter without invitation" , "to do so uninvited" , "join party unofficially" , "join party if not wanted" .)
