Expert writing Tips

Best practice

Always use the correct past participle form, "undertaken", when using "have" as an auxiliary verb. For example, write "we have undertaken a study" instead of "we have undertook a study".

Common error

Avoid using "undertook" with the auxiliary verb "have". "Undertook" is the simple past tense, not the past participle. The past participle "undertaken" should be used with "have".
