Expert writing Tips

Best practice

When using "to act on", ensure the object of the preposition 'on' is clearly defined to avoid ambiguity. For example, specify what information, advice, or principle the action is based upon.

Common error

Avoid using "to act on" when the intended meaning is simply 'to act'. The preposition 'on' implies a basis or stimulus for the action. Using it without a clear connection to something that prompts the action creates a vague or nonsensical statement.
