Don’t say: “I went to the house of my friend.”
Don’t say: “I went to my friend house.”
Say: “I went to my friend’s house.”
In English, we normally use ‘s and not OF for possessives:
- my sister’s dog
 the dog of my sister
- the teacher’s car
 the car of my teacher
- Paul’s wife’s dress
 the dress of Paul’s wife
When the word already ends in –s, just add ‘ (the pronunciation is the same):
- Jesus’ words
- our boss’ office
- my kids’ toys
