What’s the meaning of “there are more of somebody than there are of somebody”?
Solution 1:
This construction is usually (or often, anyway) used in team situations:
There were more of us than there were of them.
"More of XX" meaning more people on the team. However, it is also used (perhaps ironically/humourously) when one team has only a single person. In that case, there are always more of them than of him/her.
Solution 2:
This figure is seen when a writer or speaker wishes to portray someone battling against great odds. If I say "There are more of them than there are of me" I simply mean that I am fighting a lone battle against a large number of opponents, whether those opponents are termites or people who waste energy.
Solution 3:
"More" means number. "He" is only one against a larger number of something (people, termites etc.)
is/were seems to be the tense - present/past tense.
