Disculpe, busco la farmacia Excuse me, I'm looking for the pharmacy

Directions: commands in the usted form. Siga recto, Gire en la calle de la derecha, Cruce el parque: "go straight", "turn at the street on the right", "cross the park". The woman speaks to Pablo formally (usted). These commands are built from the yo form: drop the -o and add the "opposite" vowel. For -ar verbs it's -e: girar → gire, cruzar → cruce (before e, z is written as c). For -er and -ir verbs it's -a: seguir (yo sigo) → siga. Disculpe comes from disculpar the same way. You'll study these forms in detail at A2 (unit 15).

Si no la encuentra. "If you don't find it": here la isn't an article. It means "it" (the pharmacy, la farmacia), and it goes before the verb. Just like in English, after si (if) you use the present tense.

Formal you without usted. ¿Busca algo más?, ¿Sabe dónde está?, ¿Quiere un mapa?: the verb has the same form as for "he" or "she", but it's addressed to the listener. It's the polite "are you looking for", "do you know", "do you want". Spanish often leaves out the word usted.

Al lado del banco, delante de la iglesia. A place word + de, and de + el = del: al lado del banco (next to the bank), después del semáforo (after the traffic light). La farmacia está ahí — "the pharmacy is right there" (not far); Está allá — "it's over there" (farther away). To answer "where?", use estar.

Tengo que, sabe, conozco. ¿Tengo que caminar mucho? — "Do I have to walk a lot?": tener que + infinitive means "to have to". ¿Sabe dónde está? — "Do you know where it is?": to know a fact is saber. To know a place or a person, to be familiar with it, is conocer: No conozco el centro. English uses "know" for both.
