Though there is a slight difference between “kenkan” i.e to read and “kan” (also means to read), both can be used interchangeably. The only difference is that while “kenkan” has only one meaning, “kan” has two meanings i.e to read as well as to count. On the other hand, “didi” and “di” cannot be used interchangeably. Though the two words mean to eat, their usage differ. While didi sounds like to eat, di sounds like to consume. When then can we use di and didi interchangeably? When you have food in your hands or before you and you invite me and I’m okay and that I want to say go ahead, then I can use di and didi interchangeably. Why so? As I’m responding to your request I may be making an inaudible reference to the food before you, so in that sense I can say oh di meaning di/eat the food before you. On the other hand I can assume that I’ve not seen what is before you all even though I see something before you I don’t know what exactly it is so I’ll not make reference to it but will rather urge you to eat something. In that sense too I can say didi. So in such a situation I can use di or didi and there is nothing wrong with that. Else I’ll like to reiterate that we use didi when no reference is made to what one should eat. For example I can say didi yie meaning eat well. As to what you are going to eat I’ve not mentioned it. On the other hand, we use di with complement. That is to say we use di when we go further to tell or state the name or the type of food that one is supposed to eat. For instance one can say di Pizza – eat Pizza #learntwiwithopoku @learntwiwithopoku
