Gets out puzzles (6)
I believe the answer is:
stumps
This might be a double definition.
'gets' is the first definition.
The definition and answer can be both related to thinking as well as being verbs in their -s form.
Perhaps you can see an association between them that I can't see?
'puzzles' is the second definition.
(I've seen this before)
'out' acts as a link.
Can you help me to learn more?
(Other definitions for stumps that I've seen before include "Remains of felled trees" , "Baffles using cricket uprights" , "in match, finally drawn" , "(In cricket) close of play" , "wooden posts" .)
