Gnaeus

• (abbreviation): Gn.
• (typical abbreviation): Cn.
• (archaic or hypercorrect form): Cnaeus

According to Festus, the praenomen Gnaeus first referred to a birthmark, which was naevus in classical Latin. This etymology is commonly accepted by modern scholars. In his treatise on the origin of Roman praenomina, Chase cites the archaic spelling Gnaivos in support of this explanation.[1][2]

Gnaeus was one of a number of Latin praenomina borrowed by the Etruscans, in whose language it became 𐌂𐌍𐌄𐌅𐌄 (Cneve) or Cneies.[3][4]

• 1876, "C" in the Encyclopædia Britannica, 9th ed., Vol. IV, page 616:

  The symbol [C] retained its old value [/g/] only when as the initial letter it represented the names Gaius and Gnæus, which, in consequence, are often erroneously written and sounded Caius and Cnæus.
