Here are some examples of how to use it:
* Sọ́ nígbà tí o bá rí mí. (Speak when you see me.)
* Mo fẹ́ sọ́ pé o jẹ́ ọmọ ẹlẹ́dẹ̀. (I want to say that you are a liar.)
* Kí ni o fẹ́ sọ́? (What do you want to say?)
Keep in mind that Yoruba is a tonal language, meaning that the pitch of a word can affect its meaning. So, the tone of sọ́ is important to get the meaning right. However, it's difficult to represent tone accurately in writing.
