Language is very important part of communication in fact it carries 80% of communication. If language is not established, there would be no communication , for that communication to be, the two persons or people involve has to understand each other. It's imperative that when you come across someone , to put yourself at ease , you have to put yourself in the person's shoe so as to easily establish a link which will be later on called a communication.
To tutor or teach someone the basics of a language he or she has never heard , you have to prioritize the alphabets, once the person is able to identify and pronounce each alphabet, then we are sure pronunciation will set in and we could proceed with salutations and the rest.
I would like to make it clear that , the student has to have an interest in what ever he or she will engage in. If there's no interest , it will be hard for the tutor to inculcate into her/him the basics. Yes the tutor has an obligation to make it interesting in every session that's why ever classes will involve a lot of practical, lot of signs to explain more better each words we use so he or she could easily understand in his or her daily routine . The student has to know . it's a gradual process , so we will take everything step by step and he or she has to participate in the journey.
Wish you the best
