Expert writing Tips

Best practice

When using the phrase, ensure you clarify the scope of validity. For example, 'The ticket is valid for one entry only', specifies the context of the ticket’s validity.

Common error

Avoid assuming something is universally valid without specifying the context. Saying "His opinion is valid" without qualification can be vague. Instead, state, "His opinion is valid within the scope of personal experiences."
