Expert writing Tips

Best practice

Always use the correct grammatical form, "consists of", to ensure clarity and credibility in your writing.

Common error

Ensure the subject agrees with the verb. Using "a consists of" incorrectly suggests that the singular article "a" is the subject, leading to a grammatical error. Replace it with the grammatically correct "consists of".
