Expert writing Tips

Best practice

When intending to express an ongoing action that started in the past, use the present perfect tense with "observe". For example, use "has observed since" instead of "observes since".

Common error

Avoid using the simple present tense "observes" to describe actions that began in the past and continue to the present. This often leads to grammatical errors. Make sure to select the correct tense.
