One third/one-third

    I just googled "one third" (as in 33,3333%) and I see that at times it's hyphenated ("one-third") and other times it's not. Should it be?

    "one(-)half" also shows up hyphenated and not..

    Unless it it being used as an adjectival phrase I would not use the hyphen:
    • I own one third of this property.
    • I have a one-third share in this property.
    Personally, I would use a third or a half in all cases and thus avoid the need for a hyphen at all.

    EDIT: I was wrong! I have since learned that fractions are almost always hyphenated.

    I did consider replacing "one" with "a", but opted for "one" because it is much more frequently used - according to Google!

    Thank you for your explanation, it was very clear.

    "One third" (web: 76,300,000 - uk: 4,830,000)
    "A third" (web: 289,000,000 - uk: 22,000,000)

    In American English, the fraction 1/3 is written out this way: one-third (obviously with a hyphen).

    A third is informal. One-third is technically how the fraction should be written.

    I'd be careful with Google. There are many, many people in the world using computers, and many of the people aren't necessarily well-versed in the use of language.

    When a fraction is considered a single quantity, it is hyphenated {She has read three-quarters of the book} Chicago Manual of Style

    She has read one-half of the book.

    Yes, but I reckon that you get more hits with "a third" because a lot of phrases that include "a third world war", "a third goal" etc. are included in your hits.

    To avoid these phrases you might google:

    "one third of the total" (1.170.000 per "one third of the total".)
    "a third of the total" (270.000 per "a third of the total". )

    Manuals of style notwithstanding, hyphenated fractions that aren't being used as compound adjectives always look wrong to me.

    I would always just use "A third" for informal writing.
  10. Hello all!!
    Dictionaries do not seem to give a conclusive advice on this matter.
    Which is the more officially adopted spelling of "one third": with or without a hyphen?

    Both, sorry.
    It depends on context.
    What do you want to say about it?
    See above :)

    As a noun: He ate one third of the pie. (Grammatically the same as He ate one piece of the pie.)
    As part of a compound adjective: Each person is entitled to a one-third portion of the pie.
    Some manuals of style have mysteriously become infected with the notion that the noun form of a fraction should be hyphenated, but that is just plain wrong.

    I was taught to always hyphenate if I spell out fractions and haven't seen the need to deviate from that rule: one-third, three-quarters.

    But of course no hyphen for a third or a quarter.

    I would argue to your teachers that a and one or three are grammatical equivalents in your examples. Another angle:
    If third and share are both nouns, why would you say
    she ate three-quarters of the pie

    and not
    she ate three-shares of the pie?

    I have to say that, to me, it looks weird like that. It begs for

    "But she hasn't read the other-half of the book"

    which I've never seen (although I haven't looked on g**gle).

    Rightly or wrongly, I think I only hyphenate when it is an adjectival phrase : "They've already played three quarters of the game" but "The cup is only three-quarters full."

    A third, one third, hyphenated or not I can just imagine the Metrication Police in Brussels having a "light-bulb" moment: "Ah-ha! Another couple of words (of the people's language) that we can ban".

    Henceforth it SHALL be "33.3333%".:eek:

    Crikey,the disturbing thing is that I could really believe that this could happen.

    If you're in an environment which uses the Associated Press Stylebook, fractions less than one are spelled out using a hyphen, such as one-third. Numbers greater than one with a fractional part are written as numerals, such as 2 2/3.

    Yes. And if you are in that environment, you are in one that uses an erroneous style guide, no matter how widely used it may be.

    While with my head I agree with the people who say you shouldn't hyphenate (there's no logical reason to do so), faced with this problem in a translation for a website, I think "one third" is less clear than "one-third", which links the two words together and makes it instantly clear that this is a fraction.

    Horses for courses, as the saying goes. We can do that with English, because there's no one to tell us we can't.

    It all depends on what the "one" is.
    If "one" is a determiner, then I wouldn't hyphenate.

    Billy cut the pizza into three equal pieces. He gave one third to Amy, another third to Charlie, and the last third to Dave.

    Indeed, nice distinction.
