Defeat the leader on mound (5)
I believe the answer is:
thump
'defeat' is the definition.
The answer and definition can be both related to natural events as well as being singular nouns.
Maybe there's a link between them I don't understand?
'the leader on mound' is the wordplay.
'leader' suggests taking the first letters.
'on' means one lot of letters go next to another.
'mound' becomes 'hump' (I've seen this before).
The first letter of 'the' is 't'.
't'+'hump'='THUMP'
Can you help me to learn more?
(Other definitions for thump that I've seen before include "Dull heavy sound" , "Smack" , "Hit hard" , "Common feature of Boxing" , "Dull heavy blow" .)
