Speculate about the end of Joe Root (4)
I believe the answer is:
beet
'joe root' is the definition.
The answer and definition can be both plants as well as being singular nouns.
Perhaps you can see a link between them that I don't see?
'speculate about the end' is the wordplay.
'speculate' becomes 'bet' (to bet is to gamble or speculate).
'about' means one lot of letters goes inside another.
'end' suggests the final letters.
The final letter of 'the' is 'e'.
'bet' enclosing 'e' is 'BEET'.
'of' is the link.
Can you help me to learn more?
(Other definitions for beet that I've seen before include "The mangelwurzel, for instance" , "Sugar-yielding root" , "Genus of plant with succulent root" , "Plant grown for sugar" , "Root used as a source of sugar" .)
