Defeat and dismiss (5)
I believe the answer is:
stump
This clue might be a double definition.
'defeat' is the first definition.
(I've seen this before)
'dismiss' is the second definition.
Although both the answer and definition are verbs in their base form, I don't understand how they can define each other.
'and' acts as a link.
Can you help me to learn more?
(Other definitions for stump that I've seen before include "Part of a felled tree that's left in the ground" , "Residue after felling" , "Small remaining part; cricket item" , "defeat" , "Component of wicket" .)
