One between legs — potential cause of tears? (5)
I believe the answer is:
onion
'cause of tears?' is the definition.
(I've seen this before)
'one between legs' is the wordplay.
'one' becomes 'i' (Roman numeral).
'between' is an insertion indicator.
'legs' becomes 'on on' ('on' can mean the leg side in cricket).
'i' put within 'onon' is 'ONION'.
'potential' acts as a link.
I am not very happy about this link. It may belong to another bit of the clue.
Can you help me to learn more?
(Other definitions for onion that I've seen before include "Pungent vegetable" , "it can bring tears" , "Bulbous vegetable" , "veggie" , "Pungent edible bulb of the lily family" .)
