This document summarizes a journal article about a Korean ELL learner named Sally and compares features of the Korean and English languages. It finds that Sally struggled most with irregular verb tenses, vocabulary pronunciation, and articles. The Korean language differs from English in sentence structure and lack of articles, verb conjugation, and word stress. Korean ELLs often make errors with inflection, tense, plural nouns, and distinguishing morphemes. They would benefit from explicit grammar instruction and speaking practice with rhythm.
