"Grandmother, why do you have many teeth?"
Translation:SoSnI', qatlh Ho'Du' law' Daghaj?
I am wondering whether the 'a' in this sentence could be an error. I notice that it generally does not appear in other questions formed with interrogative pro-adverbs like nuqDaq, chay' or ghorgh.
Compare with the other sentences in the unit: ghorgh manargh, chay' chobIj or even qatlh DaHoH, none of which have an 'a'.
