If a sentence ends with "Inc." do you put two periods? Inc..

1. Nope. Only one period.

2. The real question is,

if you end a sentence with Inc. and an ellipsis, do you use 3 or 4 periods?

3. No.

Never end a sentence with multiple punctuation marks.

4. I never end sentences with "Inc."

Just doesn't sound right. ;)

5. Uh oh!! Another emergency for the Grammar Crisis Room!

According to the Blue Book of Grammar and Punctuation:

Rule 2. If the last word in the sentence ends in a period, do not follow it with another period.

Examples:
I know that M.D. She is my sister-in-law.
Please shop, cook, etc. I will do the laundry.

6. No.

An abbreviating period, however, is never omitted before a mark of sentence punctuation unless the latter is the period terminating the sentence.
