Regional Spelling Differences

We cannot properly talk about English literature without talking about the way something is written, a big part of which is spelling. A constant source of irritation with grammar snobs is the difference in dialects. Indeed, the way that the English language has developed can be very different depending on the region. Today’s post will provide a brief rundown of the most significant spelling differences between British English, American English and Australian English. Common practice is that Australian English tends to follow the rules of British English, though there are some exceptions.

In all cases, the most important thing is to maintain consistency in your writing and not to switch between styles and dialects for the same word. The best practice is to check a dictionary if you are unsure or, as we are so fortunate to be able to do, google it. The below should be a good overview of the typical spelling differences to keep an eye out for. 

For your convenience, I have provided a printable summary of everything that is below to use as quick reference whenever needed, that can be found here.

Noun and Verbs and Spelling Difference

The spelling of some words depends on its usage as a noun or verb. Best practice is to check a dictionary if unsure. Trying to distinguish between proper noun and verb usage can be difficult for spell checks to catch as the word itself is not spelt wrong, but may only be used wrongly. As such it is useful to familiarise yourself with differences.

Percent and Per cent

In formal writing, percent is usually preferred over the symbol (%). However, this often depends on the university or company style guide, so if you are unsure, that is a good place to look. It is also differently written in different dialects.
British English traditionally prefers separating the word into two, per cent whereas the US keep it as a single word, percent. Both are acceptable in either dialect. As mentioned before, the key is consistency. Pick one and stick to it.
