I noticed the following sentence, taken from Mark Twain's "The Awful German Language:"
Fifthly, I would do away with those long compounded words; or require the speaker to deliver them in sections, with intermissions for refreshments.
What is the grammatical function of the semicolon here? I would have expected a comma to be appropriate here, as to me it coordinates a dependent clause, and that would be solely under the jurisdiction of a comma, as I understood.
I thought semicolons were for replacing conjunctions between independent clauses or avoiding confusion with commas when writing a list that requires commas for one of the points within.
