Divided 100 by zero (5)
I believe the answer is:
clove
'divided' is the definition.
The answer and definition can be both to do with contact as well as being past participle verbs.
Perhaps they are linked in a way I don't understand?
'100 by zero' is the wordplay.
'100' becomes 'C' (Roman numeral).
'by' means one lot of letters go next to another.
'zero' becomes 'love' (love is zero in tennis).
'c'+'love'='CLOVE'
Can you help me to learn more?
(Other definitions for clove that I've seen before include "Garlic segment" , "Pungent spice" , "A spice; a garlic bulb" , "Dried flower bud spice" , "A small bulb as of garlic" .)
