Expert writing Tips

Best practice

When indicating that something happened before another event, use "prior to" instead of "prior of". For example, say "Prior to the meeting" instead of "Prior of the meeting".

Common error

Avoid using "prior of" to describe events happening before others. "Prior to" is the grammatically correct choice. For instance, it's better to say, "The data was analyzed prior to publication" rather than using the incorrect "prior of".

Ludwig's WRAP-UP

The phrase "prior of" is generally considered grammatically incorrect in standard English. As Ludwig AI explains, it's typically a misuse of "prior to", which is the correct prepositional phrase to indicate that something happened before something else. While "prior of" occasionally appears in various sources, its usage is inconsistent and often reflects an error. To avoid mistakes, always use "prior to" when indicating a temporal relationship. In specific, very rare, contexts, "prior of" can be correct when referencing the leader of a religious order, but such instances are uncommon.

FAQs

When should I use "prior to" instead of "prior of"?

Use "prior to" when you mean "before". The phrase "prior of" is generally considered incorrect in standard English. For example, "Prior to the event, we prepared the necessary materials" is correct.

What's a simple alternative to "prior to"?

A straightforward alternative is "before". It's less formal and often clearer. For instance, instead of saying "prior to the deadline", you can say "before the deadline".

Is "prior of" ever correct?

While exceedingly rare, "prior of" might be technically correct when "prior" refers to the leader of a religious order, as in "the prior of the monastery". However, this usage is niche, and "prior to" is far more common and versatile.

How can I remember to use "prior to" correctly?

Think of "to" as indicating direction or time leading up to something. Just like you go "to" a destination, you perform actions "prior to" an event. This association can help you avoid the mistake of using "prior of".
