"This street is familiar to me."
Translation:Ο δρόμος αυτός μου είναι οικείος.
From the comment right above yours, you'll see: "We have added γνώριμος (δρομός) γνώριμη (οδός). Οδός has been accepted from the start (we only added γνώριμη.)
Where did you have this sentence? Was "οδός" rejected? Perhaps you had an error in the adjective? Please give more details so we can clarify this.
