No, you typically don't put a period at the end of a one-word response like "yes" or "no." This is because such responses are often considered complete on their own and are not part of a longer sentence. However, if the response is part of a more formal context or is included in written dialogue, a period may be appropriate.
Because one period is signifying the shortened word (ie Dr.) and the other is just a period for the end of the sentence.
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.
Et cetera is abbreviated to etc. No second period is needed but you will sometimes find one anyway.
No, 'period' has three syllables.
If a sentence ends with an abbreviated word then only one period (full stop) is used.
Indifference
One.
Well if you want to end the sentence, you would put ONLY one period. Example: I am watching T.V. you only put one period. If the word TV is in the middle of the sentence, you still do the same Example: I am watching T.V. with my mother today.
One word.
The word 'end' contains one syllable.
A conversation-stopper, or a show-stopper.
One period. The period in etc. also functions as the period for the end of the sentence.
