"the limits (of my language) mean"

I was sent an email, and I thought I'd ask the teachers here what you all thought...

Hello

Just checked out your page and the random quote by Wittgenstein caught my eye, since I have read him, but also since the quote has the same mistake as I have seen elsewhere: \"the limits (of my language) mean .....\" and not \"means.\" Or have I missed something somewhere in my education?

There is no mistake. It is limits mean or limit means.

The subject of the sentence in question is limits.
