"We show you where our house is."
Translation:Biz sana evimiz nerede gösteririz.
In the tips at https://www.duolingo.com/skill/tr/Verbs:-Aorist- it says
"Case 1 If the root of the verb ends with a vowel; you just need to add -r to the end of the root." "Case 2 If the root of the verb ends with a consonant; In harmony with the last vowel of the root, the tense suffix may be -ar or -er."
But I could not see how either of those covered the sentence "Biz sana evimiz nerede gösteririz."
