What It Means
Think of this phrase as a verbal stamp of authenticity. It is the 'official voice' of a company or institution. When you see these words, you know the information is serious. It is not just a casual statement. It is a formal guarantee that a fact is correct. It acts like a bridge between a person and a verified record.
How To Use It
You usually place this phrase at the very beginning of a document. It often stands alone on its own line for emphasis. After the word that, you must provide a full sentence. This sentence usually includes a person's name and a specific fact. For example: This is to certify that Jane Doe has passed her exams. It is simple, direct, and very firm.
When To Use It
Use this when you are writing something that needs to be 'official.' It is perfect for diplomas, work experience letters, or medical notes. If you are a manager, you might use it to confirm an employee's role. If you are a doctor, you use it to prove someone is healthy. It gives your words a sense of legal weight and professional power.
When NOT To Use It
Never use this in a casual conversation with friends. If you say, This is to certify that I am hungry, your friends will laugh. It is far too stiff for a coffee date or a quick text. Avoid using it in creative writing or emotional letters. It is cold and clinical, which is the opposite of what you want for a heartfelt message.
Cultural Background
This phrase comes from centuries of legal and bureaucratic tradition. In the past, documents needed specific 'magic words' to be valid in court. This phrase became the standard way for institutions to speak. It reflects a culture that values written proof and formal hierarchy. It makes a piece of paper feel like a permanent, unchangeable record.
Common Variations
You might see This serves to certify that for extra emphasis. A slightly softer version is This is to confirm that. If you don't know who is reading, you might use To whom it may concern. However, This is to certify that remains the gold standard for official certificates and formal letters of proof.
Notes d'usage
This phrase is strictly for high-formality contexts. It is almost never spoken aloud; it is a written formula used to give a document authority and legal weight.
