St. Jerome (Eusebius Hieronymus), c.347-420, translator of the Bible
into Latin, the edition known as the Vulgate, was born at Stridon on
the borders of Dalmatia and Pannonia.
In his Commentary to Paul's Epistle to the Ephesians explains the
name Tychicus as 'Tychicus enim silens interpretatur,' 'Tychicus
actually means silent.'
St. Tychicus was a disciple of St. Paul and his constant companion.
He was a native of the Roman province of Asia (Acts, xx, 4), born,
probably, at Ephesus.
Also, slavic word for silent is 'tih'. Does any cognate of 'tih' in
meaning 'silent' exist in any other IE language?
