1. Pablo: ¡no! ¿Qué más dijo?
<em>In this sentence Pablo is exclaiming a negation. So Pablo says the expression </em><em>¡no! </em><em>to give more emphasis to what he is saying. Recall that in Spanish you use exclamation marks in the beginning and end of a sentence or word.</em>
2. Julio: No, hombre. Pero hay muchas computadoras en la biblioteca. Tienen la red y todo. Yo mandé un e-mail a muchos amigos y recibí la de Iris-Teresa. Es muy fácil.
<em>Computadoras </em><em>means </em><em>computers </em><em>in Spanish. So, this is a feminine noun and it is given in the plural form. So, </em><em>there are many computers </em><em>in the library.</em>
3. Pablo: Entonces, voy a la biblioteca esta tarde. Quiero ver si tengo mensajes. Tal vez también tengo un e-mail de Iris-Teresa. Posiblemente me dijo algo de José Antonio.
<em>Biblioteca</em><em> means </em><em>library </em><em>in Spanish. This is a feminine noun given in an singular form. In Spanish the definite article matches the noun both in gender and number, so that's the reason why we use the definite article </em><em>la, </em><em>that is,</em><em> la biblioteca (the library).</em>
4. Julio: Llamo del hotel
Hotel in English is the same work as in Spanish. So, the sentence <em>Llamo del hotel</em> means <em>I call from the hotel</em>
5. Julio: Para mí, no cuesta mucho. Tengo la tarjeta de crédito de mi padre
<em>Padre </em><em>means father in Spanish. There are several ways to call your father, so:</em>
<em>Papá - Dad</em>
<em>Papi - Daddy </em>
From all these words, padre is the most formal word.
