How to say it
SI · las
ˈsaɪ.ləs
Masculine
Silas
Of the forest, or short for Silvanus
What it means
Greek Silas, possibly a contraction of Latin Silvanus ('of the forest'), or possibly from the Aramaic Sheila ('asked of God'). The apostle Paul's traveling companion in the Book of Acts.
Silas appears in the New Testament's Book of Acts as Paul's traveling companion on his second missionary journey, including the famous jailbreak at Philippi. The name's exact root is debated: it may be a Greek short of the Latin Silvanus ('of the forest, woodland god'), or a Greek rendering of the Aramaic Sheila ('asked of God'). George Eliot's 1861 novel Silas Marner gave the name literary anchor. It crashed in the 20th century and is back in the US top 100 as part of the biblical-revival wave alongside Asher and Ezra. Si is the rare short; most Silases stay full.
