Formal:
* "Mo jẹ́ ti ẹ̀ títí láéláé" (Mo je ti e titi laelae) - This literally means "I belong to you forever." It is a formal and poetic way of saying it.
Informal:
* "Àwa jẹ́ ọkàn méjì" (Awa je okan meji) - This translates to "We are one heart," implying a deep and inseparable bond.
* "Mo nífẹ̀ẹ́ rẹ̀ títí láéláé" (Mo ni fe e titi laelae) - This means "I love you forever," expressing a strong and lasting affection.
Romantic:
* "Ẹ̀ jẹ́ gbogbo ayé mi" (E je gbogbo aye mi) - This means "You are my entire world," emphasizing the importance of the person in your life.
* "Ìwọ̀ nìkan ni mo nífẹ̀ẹ́" (Iwo nikan ni mo ni fe e) - This translates to "You are the only one I love," signifying a unique and powerful connection.
Choosing the best translation depends on the context and the level of formality you desire.
It's also worth noting that Yoruba culture places a strong emphasis on family and community. So, expressing your love and commitment might involve also acknowledging the person's family and friends in the statement. For example:
* "Àwa jẹ́ ọkàn méjì, ìwọ̀ àti èmi, àti ìdílé wa." (Awa je okan meji, iwo ati emi, ati idile wa) - This means "We are one heart, you and me, and our family."
Remember, the best way to convey your feelings is to speak from the heart and use words that resonate with you and your relationship.
