YOGYAKARTA Do you know what the difference between official letters and personal letters is? The term official letter refers to a letter issued by an agency or institution (government or private sector) for the sake of formal communication. Meanwhile, private letters are letters containing personal messages for non-official purposes.

Letters issued by agencies and letters made by individuals can actually be called official letters. However, private letters are more personal even though they remain formal. On the other hand, agency documents reflect the organization's authority in formal communication.

To better understand it, see the differences in official letters and personal letters in the review below.

Compiled from various sources, differences in official and personal letters can be seen from the destination, format, use of language, and sender of letters. Here's the explanation.

The official letter is addressed to official matters, agencies, or organizations. This letter usually contains official information such as permits, invitations, or assignments. Official letters also serve as legal and credible means of communication between agencies, companies, or individuals in a formal context, as well as proof of authenticity and written work guidelines.

Meanwhile, personal letters are made for personal or informal communication, such as expressing feelings and thoughts, as well as strengthening relationships with close people such as family or friends.

Official letters issued by agencies have a strict standard format. The formal or official letter structure is:

In private letters, the format is free and not bound by formal regulations. The format of the letter is as follows:

The language in the official letter must use the standard and formal language in accordance with the principles of good and correct Indonesian language, including the Enhanced Performance (EYD). The language must be short, clear, straightforward, effective, polite, and not long-winded so that the meaning is easy to understand.

Not only that, but the official letter also avoids using ambiguous terms to eliminate possible misinterpretations.

This is inversely proportional to private letters that use more relaxed and communicative language. Even so, the contents of the letter must remain polite and adapt to the level of intimacy with the recipient of the letter.

Personal letters are made by agencies or institutions, not individuals. In this letter, the identification of the sender must be clear and complete.

On the other hand, private letters written by individuals for other individuals, the identity of the sender can be more concise and not necessarily official.

Official letters made by agencies generally use formal greetings such as With respect or To Yth.

While private letters use more varied greetings and coconuts, such as 'Hello', or 'My friend'.

To your beloved hero, Rina Ameliadi Surabaya

Hello Rina,

How are you? May you and your family always be healthy and happy. It's been a long time since we last met at school last year. I really miss the moments when we study together and joke in class.

Now I'm busy studying at Malang State University, majoring in Indonesian Language Education. My collegework is quite busy, but I enjoy every process. How about you? I heard you are now working at a company in Surabaya. Have a good job and fun, huh.

Oh yes, next semester's holiday I plan to go to Surabaya for a week. If you're not busy, I'd love to meet and spend time together like before. Maybe we can take a walk to new places or just chat at our favorite cafe.

That's my letter first. I'm waiting for your letter reply, Rin. Take care of your health and enthusiasm always in your days.

Your best friend,

Kirana
