The Stoics are the go-to guys for that sort of thing. As usual, I think we only have fragments and quotations.
Panini wasn't long-winded, though. He'd be a lot easier if he were a little less terse.
There's some very complex thinking about language and knowledge in the Pali canon, but I don't know anything about post-Paninian language theorizing.
