Expert writing Tips
Best practice
When using "verified since", ensure the timeframe is clearly defined and relevant to the statement's context. This provides clarity regarding when the verification occurred and its ongoing validity.
Common error
Avoid using "verified since" with a future tense. The verification must have already occurred for "since" to be logically connected to a point in the past. For example, don't say "It will be verified since tomorrow"; instead, focus on past or present verification.
