Expert writing Tips
Best practice
Use "was at" to clearly and directly indicate someone's presence or involvement in a specific location, event, or activity. Ensure the context makes the location or activity clear.
Common error
Avoid substituting "was at" with prepositions that don't accurately convey the intended meaning, such as "was in" when specifying a particular event or activity rather than a general location. For example, say "He was at the meeting", not "He was in the meeting" to show his participation, unless referring to a location within the meeting venue.
