Expert writing Tips
Best practice
When expressing uncertainty about a past event, ensure the tense of the verb following "I was uncertain" aligns with the specific timeframe you're describing. For example, "I was uncertain whether to go" indicates uncertainty at the time of the decision, whereas "I was uncertain whether I had locked the door" refers to uncertainty about a completed action.
Common error
Avoid using "I was uncertain" when describing current uncertainties. For present-day doubts, use "I am uncertain" or "I'm uncertain" instead. "I was uncertain" strictly refers to a past state of doubt.
