Expert writing Tips

Best practice

Always ensure verb tenses agree in your sentences. "Is" denotes present tense, while "flew" denotes past tense. Use "is flying" for an ongoing action or "was flown" for a past passive action.

Common error

Avoid combining present tense auxiliary verbs (like "is", "am", "are") with past tense main verbs (like "flew"). This creates grammatically incorrect sentences. Instead, use "is flying" to maintain present continuous tense.
