What purpose does the particle に serve in this sentence?


> 人に出来ること **に** は限りがある

What is the point of the second に? Would the sentence have a different meaning
or be grammatically incorrect if it was just 人に出来ることは限りがある? Any help in
understanding this would be very helpful because I feel like I often see this
construction.




「に」is needed here because of 「ある」. This is a 「B に A がある/いる」 "There is A in/at
B" construction.

「は」is a topic marker that elevates the location/place (B) to the topic. The
subject is the thing (A) that exists.
