Cause embarrassment simply by arriving? (4,2)
I believe the answer is:
show up
'cause' is the definition.
Although both the answer and definition are verbs in their base form, I cannot see how they can define each other.
I cannot understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for show up that I've seen before include "Make an appearance" , "Put in appearance or expose" , "Arrive - put to shame" , "cause public embarrassment" , "Expose or keep appointment" .)
