Ending a Sentence with an Abbreviation
Does the period that ends the abbreviation also end the sentence?
When you end a sentence with an abbreviation, you don't need an extra period.
- Apple Computer, Inc. became Apple, Inc.. (wrong)
- Apple Computer, Inc. became Apple, Inc. (right)
The period that ends the abbreviation also ends the sentence. Think of it as an environmentally friendly rule—one dot of ink;serves two purposes.
Even though such sentences are correct, they can confuse readers who may not realize you've ended the sentence. It's best;to write out the abbreviated word if it falls at the end of a sentence or to rewrite the sentence so the abbreviation doesn't come at the end.
The story is different when the sentence is a question or exclamation—then you need both punctuation marks:
- Why did they choose Apple, Inc.?
- I adore their name: Apple, Inc.!
