Grammar Tip – Abbreviations That End a Sentence
Linden’s question: “Must the abbreviation ‘Ltd’ have a period after it? If you do use a period after it, how do you deal with the end of the sentence? Are there two periods, one for the abbreviation and one for the sentence?”
BizWritingTip response: Any abbreviation composed of upper and lower case letters should have a period after it. Therefore, Ltd. is correct.
Never put two periods at the end of a sentence. The period at the end of the abbreviation serves also as the period at the end of the sentence.
