lit., "unlettered" (grammata, "letters:" grapho, "to write"), Acts 4:13 , is explained by Grimm-Thayer as meaning "unversed in the learning of the Jewish schools;" in the papyri, however, it occurs very frequently in a formula used by one who signs for another who cannot write, which suggests that the rulers, elders and scribes regarded the Apostles as "unlettered" (Moulton and Milligan).
"unlearned" (manthano, "to learn"), is translated "unlearned" in 2 Peter 3:16 , AV (RV, "ignorant").
"uninstructed" (paideuo, "to train, teach"), is translated "unlearned" in 2 Timothy 2:23 , AV (RV, "ignorant").
Note: For idiotes, rendered "unlearned" in 1 Corinthians 14:16,23,24 , see IGNORANT , No. 4.
