Discussion

Michael Powers (PhD) Apr 5, 2009:
My answer needed punctuation as Joseph Tein correctly pointed out. The answer should read as follows: "neither: 'fifteen hours of class'"

Henry Hinds Apr 5, 2009:
This should be classified as "English-English", it has nothing to do with Spanish.
Rachel Fell Apr 4, 2009:
but... probably more than 15 hours' work (or hours of work)... Class (in this sense) isn't an uncountable and "classes" are; work isn't.

a fifteen hour class (unlikely, since it would last 15 hours straight)

15 hours of class (a total of 15 hours, split up into different segments)

When a word ends in "s", if the addition of the "s" makes the word plural, and if it is the possessor of what follows, an apostrophe is added, as in the hypothetical that Patricia mentioned.

If the singular and plural already end in "s", such as my last name (Powers), then either an apostrophe alone or an apostrophe followed by an s can be used:

Powers' books or Powers's books

If it is not the possessor, and not a contraction, such as "it's" for "it is", no apostrophe is used.

Students have 15 hours of class per week

The statement is not grammatically correct because "hours" do not possess "class". However, in a statement such as "students' classes total 15 hours each week," the apostrophe is needed.

Apostrophe

Apostrophe is needed if no prepositions is used, but I don't have my grammar books here.

No, on second thoughts, I must be wrong. I should know better.
Peer comments on this reference comment:

neutral Michael Powers (PhD) : Not in this case. That presupposes that the word with the apostrophe is either a contraction or the possessor, whereas in this case it is neither. // If I had a nickle for everyimte I have said something that I would like to retract, I would be super-rich

You are absolutely right. I added a note to my own answer before reading this. Regards.

Quasi Possessives

"Question:
Is two weeks notice supposed to be two weeks' notice?

Answer:
Although not all would agree, the Associated Press Stylebook says yes--use the apostrophe with this quasi possessive:
Follow the rules above in composing the possessive form of words that occur in such phrases as a day's pay, two weeks' vacation, three days' work, your money's worth.
Some writers, however, would regard "two weeks" as an adjective phrase and omit the apostrophe in favor of a hyphen: "two-weeks notice." Others would write "two weeks notice" without any punctuation at all.

If you're writing for a newspaper, follow the advice of the AP and use the apostrophe. If not, trust your own judgment."
Peer comments on this reference comment:

agree David Ronder : Yes, it's this type of quasi possessive and the apostrophe would not necessarily be wrong.

neutral Alejandro Alcaraz Sintes : But, in all your examples the word in the genitive denotes period of time (weeks') and rephrasable as "x lasting x weeks", and, as Mike wrote, the class doesn't last 15 hours. Or else an idiom "your money's worth" (which is explainable historically).
