If a sentence ends with an abbreviated word then only one period (full stop) is used.
No, if "etc." is at the end of a sentence in parentheses, you only need one period. The period in "etc." serves as the punctuation for the abbreviation, and there is no need for an additional period to end the sentence.
One period. The period in etc. also functions as the period for the end of the sentence.
Three periods at the end of a sentence, known as an ellipsis, are used to indicate an omission of words in a quote or a pause in speech. It can also convey a sense of suspense, trailing off, or unfinished thought.
No, you do not put an extra period after "etc." since the period at the end of "etc." serves as the ending punctuation for the sentence.
Actually it should look like this (cars, airplanes, trains, etc.). But if the sentence ends with an abbreviation, the single period will serve to end the sentence, as in cars, airplanes, trains, etc. You do not use double periods. You can, however, use a question mark or exclamation point after a period that ends a sentence. Were you talking about cars, airplanes, trains, etc.? If this looks unusual, it is because abbreviations, such as etc., are generally avoided at the ends of sentences.
No, you do not need to add an additional period if "etc." is within parentheses at the end of a sentence. The period that ends the abbreviation "etc." also serves as the sentence-ending punctuation.
no, there is only one. ================== I can't think of any example where ending a sentence with two periods would be necessary. Not even following the last word in a sentence that is being quoted within parentheses would I expect one to employ two periods. One, I humbly submit, is all that's ever needed. ------------------------- Placing more than one punctuation mark at the end of a sentence is superfluous. It is a rule of punctuation that there be only one form of "end punctuation" to a sentence. Whether the end punctuation be a period, question mark or exclamation point, only one is required. The rule applies also when the punctuation mark appears within parentheses or quotation marks; a second punctuation mark is both unnecessary and inappropriate.
"Etc" will usually come at the end of a list, so no. I believe that it is optional to put a period after it if it is not at the end of a sentence.
they are just there to help you start off or end a sentence
Yes. Etc. is an abbreviation. yes yes yes yes yes
Yes, when using a double period abbreviation (like "etc." or "e.g."), you should only use one period at the end of a sentence. The abbreviation's final period serves as the sentence's concluding punctuation. Therefore, it should appear as "She enjoys outdoor activities, such as hiking, biking, etc." instead of "etc..".
Twice, with a comma before and between, like this: The frumpy lecturer went boringly on and on ad infinitum and even beyond, etc, etc.
