In my project, I will analyze at the debate of whether English is affecting the use of the subject personal pronoun in Spanish in the United States. In English, the subject personal pronoun is more or less obligatory—speakers cannot just say “Went to the store”; they must say “I went to the store”. However, in Spanish, “Fui a la tienda” is the same as saying “Yo fui a la tienda” because the first person singular reference is built into the verb conjugation. I will look at research asserting that there is an increased use of the SPP in Spanish speakers of the US because of its contact with English, as well as research asserting that English has not affected its use. More generally, I will look not only at the subject personal pronoun, but contextualize it with some history of change in the English and Spanish languages, as well as how language changes when in contact with another language.
