Fall awkwardly (6)
![Ross](/clue/static/ross-mug.min.png)
I believe the answer is:
tumble
'fall awkwardly' is the definition.
(I've seen this before)
This is all the clue.
(Other definitions for tumble that I've seen before include "Fall awkwardly" , "Roll over and over like acrobat or pigeon" , "An acrobatic feat of rolling or turning end over end" , "Suddenly fall" , "Fall clumsily" .)
