In English, everything simply just is. The to be verb can be used when stating, I am a girl, He is 32 years old, or They are at the house. Also notice that in english the "to be" verb also changes or is conjugated based off the pronoun, ie: "is, are, am."
The way Igbo people conceptualize the "to be" verb is different however. In this episode we explain that the "Ịbụ" "to be" verb in Igbo is used more when expressing a category of an object or its literally "being" while "Ịdị" is more so used to qualify that being or to speak towards an attribute. There is another form of the "to be" verb in the igbo language used to explain "to be at a place," (explored in the next upcoming episode).
