تهانينا

You can use it exactly like the English word 'Congratulations!' It works perfectly as a standalone exclamation. If you want to be specific, add the word على (on) followed by the achievement. For example, تهانينا على النجاح means 'Congratulations on the success.' It is easy to pronounce and fits into almost any sentence structure. Just say it with a smile, and you are good to go!

Use this when a friend gets a promotion or a sibling graduates. It is perfect for weddings, new babies, or even when someone buys a new car. In a professional setting, it is the safest way to congratulate a colleague. You can also use it in text messages or greeting cards. It is like the 'Swiss Army knife' of Arabic celebrations. If someone did something good, this word fits.

Avoid using this for somber occasions, obviously. Do not use it if someone tells you they are quitting a job they hated—unless you are 100% sure they are happy about it. Also, while it is versatile, do not use it for very minor things. If someone just found their lost keys, a simple 'Alhamdulillah' is better. Using تهانينا for trivial things might sound like you are being sarcastic. Nobody likes a sarcastic 'congratulations' when they are just trying to get through the day.

In Arab culture, joy is rarely a solo performance. It is a communal experience. The 'na' at the end of تهانينا means 'our.' This reflects the cultural value that one person's success brings pride to the whole group. Historically, celebrations in the Arab world involve large gatherings and shared meals. By saying 'our congratulations,' you are placing yourself within that circle of support. It is a beautiful linguistic nod to community and shared happiness.

The most common alternative you will hear is مبروك (Mabrouk). While مبروك is used everywhere, تهانينا sounds slightly more elegant and formal. If you want to go big, say ألف مبروك (A thousand congratulations). In very formal writing, you might see أجمل التهاني (Most beautiful congratulations). For a religious touch, people often add ما شاء الله (God has willed it) before or after to protect the person from the 'evil eye.'
