Suits was born in the parish of Võnnu to Teacher Hindrik Suits and Liis Suits (née Kerge). He had an older sister, Ann. In 1895, Suits moved to Tartu, Estonia to study at the Alexander Gymnasium. Suits so enjoyed this bustling university town and its intellectual centers that he became determined to become a part of its literary society. By the time he was 16 years old, the newspaper Uus Aeg (New Time) published his first critical essay. In 1899, the newspaper published his first poem, Water Lilies.
