This is a very minor thing, but do any of you grammar Nazis know the correct way of ending a sentence with the abbreviation for “and so forth”? The abbreviation is, of course, “etc.”, ending with a period. However, at the end of a sentence does that period suffice to do the dual duty of terminating the abbreviation and simultaniously ending the sentence? Ending the sentence like this “blah blah blah blah etc…” with two periods looks silly. I’ve been avoiding this by using the full “and so forth” phrase as a sentence ender, but that seems long winded.
Please help with this longstanding void in my knowledge.
