Expert writing Tips

Best practice

Always use an auxiliary verb (have, had, etc.) with "undertaken" to form the correct tense. For example, use "I have undertaken" or "I had undertaken" instead of "I undertaken".

Common error

Avoid using "undertaken" without a helping verb such as "have", "has", or "had". This omission creates a grammatically incorrect sentence.
