To tell someone something, especially in a formal or official way.
“I am writing to inform you that I will be unable to attend the meeting.”
“Please be informed that the shipment was delayed by two weeks.”
'Inform' is useful in CELPIP Writing Task 1 when the task requires you to notify someone of a decision, change, or problem, such as informing a landlord about a leak. It sounds more professional than 'tell,' which helps keep your tone consistent in formal emails.
Synonyms: notify, advise, let (someone) know
