What It Means

Think of this phrase as a professional bridge. It links your current email or letter to something the other person sent earlier. It tells the reader exactly why you are contacting them. It acts like a mental bookmark for a previous conversation. It is very precise and clear.

How To Use It

You usually put this right at the start of your message. It is the very first sentence after the greeting. Most people follow it with a date or a specific topic. For example, you might say With reference to your letter of June 10th. It sets a serious, organized tone immediately. Always follow the introductory phrase with a comma before starting your main point.

When To Use It

Use this when you are dealing with official business. It is perfect for writing to a bank or a lawyer. Use it when applying for a job or responding to a formal complaint. It shows you are paying attention to details. It makes you look like a pro who keeps good records. It is great for paper mail or very formal emails.

When NOT To Use It

Never use this with your best friend. Do not use it in a casual WhatsApp group. If you text your partner With reference to your letter about dinner, they will think you are joking or mad. Avoid it in modern, fast-paced tech startups. It can feel a bit 'stiff' or old-fashioned in casual offices. If the vibe is 'jeans and t-shirts,' use Regarding instead.

Cultural Background

This phrase comes from a time when business was done entirely on paper. Clerks needed a way to track long chains of correspondence. It has a very British, civil-service feel to it. It suggests a world of filing cabinets and fountain pens. Today, it survives as a 'gold standard' for formal English across the globe. It signals that the matter is being handled officially.

Common Variations

You can swap this for Regarding your letter to sound slightly less stiff. Further to your letter is another popular choice in the UK. If you want to be very modern, just use About your letter. Some people use In response to your letter if they are answering a specific question. In relation to is another cousin of this phrase.

使い方のコツ

This phrase sits at the high end of the formality scale. Use it when you want to establish a clear, documented trail of communication in professional or legal settings.
