Grind a particle? Many, many more (7)
I believe the answer is:
million
'many many more' is the definition.
The answer and definition can be both quantities as well as being singular nouns.
Perhaps they are linked in a way I don't understand?
'grind a particle?' is the wordplay.
'grind' becomes 'mill' (synonyms).
'a particle?' becomes 'ion' (I've seen this before).
'mill'+'ion'='MILLION'
Can you help me to learn more?
(Other definitions for million that I've seen before include "A thousand thousnad" , "A thousand thousands" , "Ten to the power of six" , "What mega means" , "A power of 1 Down" .)
