If you want. I've heard that an apostrophe with letters in numbers is an American thing. I've also heard that the Brits do it differently. I'm American and I don't use an apostrophe with letters and number as long as there is no confusion to the reader.Examples:1300s or 1300'sABCs or ABC'sBoth examples are correct. It is my opinion that there is little chance of the reader becoming confused.Examples when lack of an apostrophe might confuse the reader:Mind your p's and q's.Always remember to dot your i's and cross your t's.Answer 2:Apostrophes are commonly, but erroneously, used in numbers such as calendar decades or centuries instead of using the correct form, e.g. 1800s or the 1970s. According to the Oxford Dictionary, numbers used in this format should not have an apostrophe. It is acceptable (though not a rule) to use it for individual numbers such as "count in 7's as far as 100". Though acceptable, it is unnecessary.In some situations it is acceptable to use an apostrophe to clarify a plural for lower case letters only - again, the Oxford Dictionary states that it is incorrect to use it for capitals. ABCs is correct. ABC's is not.
With numbers and acronyms, use an apostrophe s. When in doubt, you can always spell it out.
20s is correct.
In contractions and to show possession
I've sometimes used the abbreviation Rec'd. Yes, because an apostrophe indicates contraction: missing letter(s) -- in this case, the e, i, v, and last e. A writer would not want to use more than one apostrophe in a single word, hence: Recvd would logically be punctuated as: Rec'v'd -- requiring more than one apostrophe and more work than an abbrev. calls for! ;-) --Good question. Thanks for asking.
The correct spelling is apostrophe.
yes
Unless it means "it is", there is no apostrophe in "its". See related question.
Yep :)
A possessive pronoun does not take an apostrophe. This is an exception to the rule that an apostrophe indicates the possessive. To write, 'the dog lost it's bone,' is not correct. The correct way is without the apostrophe: 'The dog lost its bone.' 'It's' (i.e., with an apostrophe) is correct only when used as a contraction of 'it is.'
Yes, there can be either apostrophe s ('s) or just an apostrophe (') at the end of the word.
Yes, that is correct. Program belongs to year.
No, the word is spelled "employees" that's correct.
Yes. Salesman's license is correct.
It's is the contraction for it is....so if you are using the contraction, use the apostrophe. If you are not, then do NOT use it.
The correct use of the apostrophe for a sign that reads "The Jakob's" should be "The Jakobs'" if it refers to something that belongs to multiple people named Jakob. If it refers to something belonging to one person named Jakob, it should be "The Jakob's."
