Expert writing Tips

✓ Best practice

Use "half of which" to clearly indicate that you are referring to exactly 50% of a previously mentioned group or quantity. Ensure the antecedent is unambiguous for clarity.

⚠ Common error

Avoid using "half of which" when referring to singular nouns or uncountable nouns where dividing into halves doesn't make sense. For example, it would be incorrect to say "the water, half of which was polluted" since water is uncountable. Instead, use "part of which" or rephrase the sentence.
