Capítulo 2: Mis amigos y yo - Notes

2.1 Adjectives (pg. 49-50)

  • What is an adjective?

    • Words such as alto, triste, and joven are adjectives (los adjetivos) and they describe nouns.

    • In Spanish, adjectives often change their form to agree with the noun they describe.

  • Forms and agreement for adjectives ending in -o

    • Adjectives ending in -o must agree with both gender and number of the noun.

    • Gender: masculine = ending -o; feminine = ending -a.

    • Number: singular vs. plural indicated by -singular forms; plural indicated by -s (for words ending in a vowel) or -es (for words ending in a consonant).

    • Masculine singular example: el hombre alto

    • Masculine plural example: los hombres altos

    • Feminine singular example: la mujer alta

    • Feminine plural example: las mujeres altas

    • Rule recap: Masculine -o; Feminine -a; Plural -s as a general rule; if a consonant ends the stem, use -es for plural.

  • Forms for adjectives ending in -e or consonants

    • Adjectives that end in -e (e.g., triste) or that end in a consonant (e.g., joven) agree only in number with the noun (gender does not change).

    • Plural endings for these adjectives: add -s or -es to indicate plural; masculine and feminine forms are the same for these endings.

    • When adding -es to form the plural, an extra syllable is added, so sometimes an accent mark is needed to preserve stress.

    • Example given: joven → jóvenes

  • Quick reference table (agreement rules)

    • SINGULAR | PLURAL

    • Masculine: el hombre alto | los hombres altos

    • Feminine: la mujer alta | las mujeres altas

  • Rule for choosing between -s and -es

    • If the word ends in a vowel, add -s.

    • If the word ends in a consonant, add -es.

    • This rule mirrors the noun pluralization pattern seen in Estructura 1.2.

    • Note: When adding -es, stress may shift; use accents as needed (e.g., joven → jóvenes).

  • Quick takeaway

    • -o adjectives: must reflect gender and number.

    • -e or consonant endings: reflect number only; gender remains the same.

2.2 The verbs estar (to be) and ir (to go) (p. 53)

  • In Para empezar, two new verbs were introduced: estar (to be) and ir (to go).

  • Conjugation practice: fill in the blanks using the forms from Para empezar.

  • Conjugation chart (present tense)

    • SINGULAR

    • yo: estar = estoy, ir = voy

    • tú: estar = estás, ir = vas

    • él/ella, usted: estar = está, ir = va

    • PLURAL

    • nosotros/nosotras: estar = estamos, ir = vamos

    • vosotros/vosotras: estar = estáis, ir = vais

    • ellos/ellas, ustedes: estar = están, ir = van

  • Subject pronouns (often omitted in Spanish)

    • Examples:

    • Estoy contenta. = I’m happy.

    • Están aburridos. = They are bored.

    • Vamos a la fiesta. = We’re going to the party.

    • ¿Vas a clase? = Are you going to class?

  • Formal vs informal addressing (usted vs tú)

    • The form used to address someone formally (usted) differs from informal (tú).

    • Transformation examples (from tú form to usted form):

    • ¿Cómo estás? → ¿Cómo está usted?

    • ¿Vas a la fiesta? → ¿Va usted a la fiesta?

  • Distinction between ser and estar

    • Estar expresses temporary states or conditions (not lasting):

    • Estamos cansados. (We are tired.)

    • ¿Estás enferma? (Are you sick?)

    • Ser expresses more permanent characteristics or origins:

    • Soy de Guatemala. (I’m from Guatemala.)

    • UCLA es una universidad. (UCLA is a university.)

    • More on ser vs. estar covered in Estructura 4.4 and 5.3.

2.3 The verb gustar (pg. 56)

  • Me gusta vs. me gustan

    • Both mean “I like,” but usage depends on what follows:

    • Me gusta [infinitive or singular noun]; Me gustan [plural noun].

  • Me gusta and me gustan examples (from Para empezar):

    • me gusta la música

    • me gusta la biología

    • me gustan las películas

    • me gustan los deportes

    • me gustan los libros

  • Singular vs. plural in gustar constructions

    • When a single item or an infinitive follows gustar, use the singular form: me gusta [singular noun or infinitive].

    • When multiple items follow gustar, use the plural form: me gustan [plural noun].

    • Table (conceptual):

    • me gusta con un sustantivo (singular noun) or con un infinitivo

    • me gustan con un sustantivo (plural noun)

  • Te gusta / Te gustan

    • Te gusta and te gustan function like me gusta/me gustan, with form depending on singular/plural subject.

    • Example prompts: ¿Te gustan los deportes? ¿Te gusta la historia?

  • Le gusta / le gustan

    • Le gusta and le gustan mean he/she likes or you (formal) like.

    • To clarify who is being talked about, you may use a + name or a pronoun (e.g., a usted).

    • Example prompts and answers:

    • ¿A usted le gustan las novelas gráficas?

    • A Carolina no le gusta el chocolate.

2.4 Infinitives with gustar and ir (p. 58-59) (1-3)

  • Infinitivo (infinitive) after gustar

    • In Para empezar, me gusta is followed by the infinitive (el infinitivo), the unconjugated form of the verb.

    • Infinitives in Spanish end in one of these: -ar,
      -er,
      -ir.

  • Examples of infinitive endings (types):

    • -ar verbs: estar, hablar, usar

    • -er verbs: hacer, tener

    • -ir verbs: dormir

    • These three endings correspond to the three verb groups in Capítulo 3.

  • Gustar with infinitives (singular)

    • Gustar is always in the singular form when used with one or more infinitives.

    • Examples:

    • Me gusta ir al cine. (I like to go to the movies.)

    • A José le gusta escuchar música y bailar. (José likes to listen to music and dance.)

  • Infinitives with ir a (to express a future event)

    • Infinitives are used after ir a to express a future action:

    • Voy a estudiar. (I am going to study.)

    • Van a nadar. (They are going to swim.)

    • ¿Vas a correr? (Are you going to run?)

    • Ana va a usar la computadora. (Ana is going to use the computer.)

  • Summary note on usage

    • me gusta + infinitive = I like to + verb

    • ir a + infinitive = going to do + verb (future)
