Studies on first language acquisition addressed this complex process from different aspects and provided explanations for some of the issues involved in the process. Many FLA studies are centered on Indo-European languages with the bulk of research still concentrated on English (Stoll, ۲۰۰۹). Persian, as one of those less-researched languages, is the focus of the present study. Limiting the scope of the study, it was desired to investigate the types of errors made by a three-year-old child in the process of his FLA. All speech errors of the child were recorded for three months. The errors were classified into five categories of pronunciation, vocabulary, grammar, pragmatic-semantic, and incorrect innovation. Some of the child's errors were due to metathesis, loss and partial oral motor control for pronunciation errors, overextension for vocabulary errors, and overgeneralization for grammatical errors. Pragmatic-semantic errors were due to the child's unfamiliarity with the secondary meaning of the words
