Expert writing Tips

Best practice

Always double-check ordinal numbers like "fourth", "fifth", etc., to ensure correct spelling. Using the proper spelling enhances clarity and credibility.

Common error

Avoid using "forth" when you mean "fourth". "Forth" means 'out' or 'onward', while "fourth" refers to the ordinal number 4. For example, use "fourth" when indicating the fourth item in a list.
