It is explained throughout the study that the use of several native English resources complemented the acquisition of the English language. For this study, a descriptive method was used. The Wug test was applied to the subject to determine the level of acquisition of the plural morphemes, third person singular morphemes, and past tense morphemes of regular verbs. Finally a comparison of 2011 Wug test and 2014 test is made to determine mastery of these morphemes in a period of three (3) years. The results proved that the subject did acquire naturally the studied morphemes and the Wug test shows some aspects of the interlanguage development related to the acquisition of morphemes done by the subject of the study.]]></p></abstract>
<abstract abstract-type="short" xml:lang="es"><p><![CDATA[ResumenEste estudio de caso centra su mirada detenidamente en la adquisición bilingüe de una lengua de una niña costarricense que aprendió dos idiomas como su primera lengua a través de los métodos OPOL -One Parent One Language- (Un Padre, Un Idioma) y Minority Language at Home (mL@H) (La Lengua Minoritaria en el Hogar). Itzel, el sujeto de este estudio de caso, creció en un ambiente donde la lengua nativa o el idioma nativo es el español desde su nacimiento hasta su edad actual. La única persona que le habló en inglés fue su padre y para ello se complementó con recursos que desarrollaban este idioma. Se utilizó la metodología descriptiva para el estudio de casos. Además, se aplicó el examen "Wug", de Berko Gleason, para determinar el nivel de adquisición de los morfemas de los plurales de sustantivos, la tercera persona de los verbos y el pasado simple en inglés. Se hace una comparación entre los resultados del mismo examen aplicado al sujeto en el 2011 y luego en el 2014 en un período de tres (3) años, en el cual se comprobó un progreso en la adquisición de los morfemas estudiados, pues esta prueba muestra algunos aspectos del desarrollo del interlenguaje relacionado con la adquisición de morfemas.]]></p></abstract>
