The Basics: Penblwydd Hapus
The most direct and common way to say happy birthday in Welsh is Penblwydd Hapus. Let us break down this essential phrase so you can understand exactly what you are saying to your loved one.
The word Penblwydd translates to birthday. It is a compound word where pen means head or end, and blwydd means year, essentially marking the completion of another year of life. The word Hapus simply translates to happy. Unlike in English where the adjective comes first, the Welsh language typically places the adjective after the noun, which is why it is structured as birthday happy.
Pronunciation is often the biggest hurdle for non-Welsh speakers, but it is easier than it looks. You pronounce it as: Pen-blooyth ha-piss. The dd in Welsh produces a soft th sound, similar to the th in the English word this or that.

7 Unique Ways to Wish Someone a Happy Birthday in Welsh
While Penblwydd Hapus is perfect on its own, adding a few extra words can tailor your message to the specific person you are celebrating. Here are seven detailed examples and practical phrases you can use to craft the perfect Welsh birthday greeting.
- Penblwydd Hapus i ti: This translates to Happy birthday to you. The phrase i ti is the informal singular version of to you. This is the exact phrase you should use when figuring out how to wish a friend a happy birthday or when speaking to a close family member or child.
- Penblwydd Hapus i chi: This also translates to Happy birthday to you, but i chi is used in formal situations or when addressing more than one person. Use this for an older relative, a colleague, or an acquaintance to show respect.
- Penblwydd Hapus fy nghariad: This beautiful phrase means Happy birthday my love. The word cariad means love or darling. Due to Welsh grammar rules regarding nasal mutation after the word fy (my), cariad becomes nghariad. This is the perfect addition to romantic happy birthday wishes for your love.
- Mwynha dy ddiwrnod: This translates to Enjoy your day. It is pronounced mween-ha dee theer-nod. It is a fantastic follow-up sentence to write inside a greeting card right after wishing them a happy birthday.
- Iechyd da: This famous Welsh phrase translates to Good health and is the standard way to say Cheers! If you are handing the birthday person a pint or a glass of champagne, raising your glass and shouting Iechyd da (pronounced yech-id dah) is a must.
- Cofion gorau: Meaning Best wishes, this is a brilliant sign-off for the bottom of a birthday card before you sign your name. It adds a polite, warm, and traditional touch to your written messages.
- Penblwydd Hapus yn 50 oed: If you want to specify a milestone age, you use the formula Penblwydd Hapus yn [Age] oed. For a 50th birthday, this translates to Happy 50th birthday. You can swap the number for any age you are celebrating.

No birthday party is complete without a song. If you are gathering around a cake lit with candles, you might want to surprise the guest of honor by singing the traditional tune in Welsh.
