One’s lowest digit? (3)
I believe the answer is:
toe
This could be a double definition.
'one's' is the first definition.
Both the definition and answer are adjectives. Perhaps they are linked in a way I don't understand?
'lowest digit?' is the second definition.
(digit low on the body)
Can you help me to learn more?
(Other definitions for toe that I've seen before include "'Little piggy'" , "compliantly put on line" , "Digit on foot" , "low digit" , "Conform or obey; ... the line" .)
