This study aims to analyze various types of errors found in the writings of female marriage-based immigrants from Korean language intermediate classes in Korea, in order to examine the education of Korean particles for female marriage-based immigrants. Among the various errors in using Korean particles many female marriage-based immigrants make, the most frequently made was the replacement of particles, followed by omission and addition of particles due to insufficient knowledge of the language that they are not sure whether a particle is needed or not in a sentence as a component. And when they do not have sufficient knowledge of the morphology of particles, they make errors such as spelling errors as well as paraphrasing in some cases, where particles were replaced with other parts of speech or phrases. Therefore, in teaching Korean particles, first of all, it is important to make them to understand the role of particles in a sentence, and the meaning and function of each particle in relation to predicates together with the morphology have to be taught for correct usage as well. The particles with high rate of frequency in usage and high rate of making errors include: ‘이/가, 을/를. 은/는. 에, 의, 에서, (으)로, 와/과, 에게, (이)라고, 한테’. Therefore, it is necessary to structure textbooks centering on the particles that are the most frequently used and easy to make mistake. And the textbooks should also include examples of wrong particle usage as well as the difference between correct usage and mistaken usage. However, some Korean textbooks mainly used in teaching the female marriage-based immigrants at present do not include any chapter dealing with the main particles, and also there is not enough explanation of the difference between particles that are often mistaken, either, which also need to be supplemented.
