SER

SER is a irregular verb that consist of am (soy), are (eres), is (es), somos, sois, and son.  I learned that soy, eres, es, somos, sois, and son mean different things. I also learned that you don't have to use subject pronouns in spanish.  You can put emphasizes on words such as yo but you can also clarify words by using el, ella, ud.
