A letter to a teacher; verbs that fit the sentence

A letter starts with a greeting: Hurmatli ustoz! (Dear teacher!). Then we say what we want to write about. At the end come a wish and a signature (name, date). In a letter to a teacher we respectfully say «Siz» (you, polite). Letters are lively when full of verbs: o‘rgatdingiz (you taught), tushuntirdingiz (you explained), yordam berdingiz (you helped).
