Expert writing Tips
Best practice
When using "on either occasion", ensure that the two occasions you are referring to are clearly defined or have been previously mentioned in the text to avoid ambiguity.
Common error
Avoid using "on either occasion" when you mean "on each occasion". "Either" refers to one of two options, while "each" refers to every one of the options. For example, don't say "The outcome was poor on either occasion" if the outcome was poor at every opportunity; instead, use "The outcome was poor on each occasion."
