I know there are other questions comparing the US and UK usage of o and ou in words like colour. My question is specifically in regard to Australian English. I was always taught that here in Australia we use ou and that the other variant was yet another example of the insidious corruption of civilization as we know it by our cousins across the water. However, recently I've been reading old newspaper reports from the early 1900s and have consistently found them writing color, honor, etc. I wonder if anyone knew when and why this changed.

As an example in a newspaper see the excellent trove in this article.

  • One has to wonder if this doesn't have something to do with the fact that both countries were originally populated from roughly the same class of English socieity (prisoners).

    I would hazard a guess that there was some sort of political reason for changing to UK spellings.

I have researched this topic as well. I would like to point out a few aspects to this discussion that may be useful. First of all, it is correct (and Wikipedia says so as well) that today's Australian publications, including newspapers and digital media, almost without exception (except for certain proper nouns such as the Labor party and Victor Harbor) follow the UK norm of "-our" endings. It is correct that several Australian publications in the 20th century preferred the "-or" endings. Newspapers such as "The Age" from Melbourne and "The Advertiser" from Adelaide used the American "-or" spellings until the middle of the 1990's. They changed to British spellings in the second half of the 1990's probably with the advent of digitised and computerised publications. I think a similar trend occurred in Canadian newspapers as well.

I should add, though, that it is probably not accurate to claim that Australian spellings "changed" from American to UK norms. This gives the spurious impression that American spellings used to be preferred to UK spellings in the early 20th century. That seems to have never been the case as I argue below.

First of all, even when "-or" endings were more conspicuous in Australia, they were certainly not exclusive and co-existed with "-our" endings. For a Victor "Harbor" in South Australia, spelt without the "u", there was a Sydney "Harbour" bridge that was always spelt with the "u". Also, the "-or" spellings were probably the ONLY instances of American spelling norms co-existing in Australian publications. The more conspicuous differences such as "realise", "organise", "analyse" were always spelt using British/Commonwealth norms instead of the American style of ending with "-ze", as were "theatre" and "centre" or even "manoeuvre" (American spellings prefer "-er" endings), as also were "modelling" and "travelling" (American english prefers single "l"). It is, therefore, not correct to say (only on the presence of "-or" endings) that Australian spellings used to be closer to American spellings in the past. That seems never to have been the case. In fact, in spite of the use of "-or" endings, overall Australian spelling norms have always been closer to UK norms.

This, in my mind, also belies the argument that the prevalence of American dictionaries were the cause of American style spellings. I think the "-se/-ze" differences between American and British spellings are much more frequently seen in writings across the world than the "-our/-or" endings. Had American dictionaries been that influential in Australia, then the "-ze" endings (and the "-er" endings) would have likely been adopted in Australia as well. They never were.

To my mind, the most logical reason for the almost universal acceptance of British spelling norms in today's Australian English, including the apparent abandonment of the "-or" endings, took place because the "-or" endings, though seen more often in the early 20th-century than now, were never dominant and were still considered somewhat anomalous. With spell-checkers and computerised publishing, it would be easier to follow one norm, either UK or US, for spellings. The UK spellings were adopted probably because they were always more prevalent. Today, the only conspicuous American spelling in Australian media comes from the Australian "Labor" Party due to historical and political reasons (although "labour" with the "u" is the preferred spelling in all other contexts), and the use of the spelling "program" instead of "programme" in all contexts. Note that the Democratic Labo(u)r Party in Australia, that used to also spell "Labor" recently switched back to the UK spelling with the interesting comment: "Putting (YOU) back in Labo(u)r!" Perhaps the Australian Labor Party will also bring the "u" back in Labor in the not so distant future.

Finally, the near future of Australian spellings seems to be much more closely aligned with British norms. UK spellings are taught in schools, and in spite of Americanisms pervading all aspects of Australian society, including language, Australians probably will likely not change to American spellings because doing so may appear as a new type of cultural colonialism. If Canada, the next-door neighbour of the US, retains mostly UK spellings, it is difficult to see how and why Australia would switch to US spellings. Funny that all the commonwealth nations (read India, Pakistan, Singapore, Hong Kong) have taken to shunning so many practices of their colonisers (the British), but have all retained their spellings!

  • Very interesting answer. I can say with certainty, however, that Canada was using British "-our" spellings at the beginning of the 1970s when I attended high school there. I remember having to alter a lot of the spellings that I had grown up with in Texas. I suspect that the Canadian spellings always followed the British models—and its having done so calls into question the rationale of the U.S. dictionary argument as applied to Australia: if any country's spelling should have been influenced by U.S. spelling conventions, Canada's should have.

Well, you missed off the connected question, why is the spelling of the Australian Labor Party using the 'or' form. Wikipedia is inconclusive on the topic. From what I read on it while researching the ALP it was either a homage to the US labor movement or it was a common spelling at the time.

Wikipedia has a note on Australian English in the late 19th until the mid 20th century.

I think it is probably due to editorial decisions at newspapers from that time because the same usage does frequently occur in Australian books from the same period. If anyone has a copy of any Australian style guides or editorial guidelines from that time I'm sure we could answer this question.

I have some dictionaries and books on writing from late 19th century so I'll update this later if I find anything.

Don't dismiss the inability of editors in small town and regional newspapers as a possibility either. Australia has a long history of incompetence in that department.

Update 1: I found this article which references an article from before Australian Federation (pre-1901) that blames the problem on the availability of American dictionaries. The article cites papers that I can't find online but they are probably hiding in some upstairs section of a university library.

  • Thanks, I was going to mention the Labor anomaly. I'm sure I've heard a reason, but can't recall. I should do a search on trove and see what statistics come up for different decades - stay tuned.

    Be sure to include the names of the newspapers. Sometimes spelling is determined by politics. That is, the newspaper may have had a strong anti-UK bias or pro-American bias (this one is much rarer in Australian writing before World War 2).

    Thanks, my preliminary look seems to show consistent usage across SMH, Argus, plus lots of smaller local papers, but I'll keep gathering some stats.

The change from American spelling to British spelling is, surprisingly, a recent phenomenon in Australia. It was standard for most of the 20th century for Australian newspapers to prefer the '-or' ending to the '-our' ending. Strangely, words such as 'centre' and 'theatre' were generally spelled in the British style. It is only in recent years that Australian newspapers have begun using the British '-our' endings. Perhaps contacting the newspapers directly would help shed some light on the subject. Also, it wasn't just newspapers that preferred the American '-or' endings. Magazines such as TV Week advertised their 'full color' poster each week, while Channel 9 proudly displayed the logo 'Living Color' from 1975 onwards for several years after the introduction of color television in Australia. In fact, you'll find an example of this 'Living Color' logo on the internet (a blast from the past!). I have a dictionary published by the Herald and Weekly Times setting out its standard for Australian spelling. It reflects the spelling usages above. Many younger Australians may be surprised to learn that the change of usage from American to British spelling and grammar in Australia is a very recent phenomenon.

  • I seem to recall the Australian Government dabbled with a simplified spelling sometime during the 20th century. The spellings were simplified drastically. It didn't take off though, and I assume these 'Americanised' spellings are the remnants of that.
