pe.ti denotes an inexperienced or undiscerning person, especially one needing instruction or exposed to poor judgment.

The term consistently identifies people marked by inexperience or insufficient discernment: they may accept every word, continue into danger, or need instruction, while wisdom and knowledge are set before them as the contrasting path. The same designation can also occur where such people receive preservation, understanding, or provision for atonement.

   In Proverbs 14:15 the masculine singular noun stands against the prudent person: the APB renders the clause, "The simple is faithful to every word, but the prudent understands his step." Plural forms describe people who inherit folly, pass by danger, lack heart, or are called to gain prudence and understanding in Proverbs 14:18, Proverbs 22:3, Proverbs 7:7, and Proverbs 8:5. The designation also marks those to whom knowledge is given or who receive preservation and understanding in Proverbs 1:4, Psalm 116:6, and Psalm 119:130.

In the Anselm Project Bible: Across the occurrences, the APB commonly uses "simple" or "simple ones" in clauses about instruction, folly, danger, and preservation. In Psalm 19:8, the supplied translation does not isolate the term with a corresponding English expression, so its specific contribution there cannot be identified from the English wording alone.
