Hold nothing dear? (4)
I believe the answer is:
love
This could be a double definition.
'hold nothing' is the first definition.
'love' can be an answer for 'nothing' (love means zero in tennis). I am not sure about the 'hold' bit.
'dear?' is the second definition.
(I know that dear can be written as love)
Can you help me to learn more?
(Other definitions for love that I've seen before include "Fondness" , "associated with a cold climate?" , "Deep affection" , "Adoration" , "Intense affection" .)
