1. The Imperative Mood (Commands)

Commands differ based on two key factors: formality (tú vs. usted/ustedes) and polarity (affirmative vs. negative).

Informal Commands (Tú)

• Affirmative Tú Commands: Use the 3rd-person singular present indicative (él/ella) form.
  • Hablar $\rightarrow$ ¡Habla! | Comer $\rightarrow$ ¡Come! | Escribir $\rightarrow$ ¡Escribe!
• Irregular Affirmative Tú Commands (8 Verbs): Remember them with the phrase "Vin Diesel has ten weapons" (ven, di, sal, haz, ten, ve, pon, sé):
  • Decir $\rightarrow$ di | Hacer $\rightarrow$ haz | Ir $\rightarrow$ ve | Poner $\rightarrow$ pon
  • Salir $\rightarrow$ sal | Ser $\rightarrow$ sé | Tener $\rightarrow$ ten | Venir $\rightarrow$ ven
• Negative Tú Commands: Use the present subjunctive tú form (tú form opposite vowel + -s).
  • ¡No hables! | ¡No comas! | ¡No escribas! | ¡No hagas! | ¡No digas! | ¡No vayas!

Formal Commands (Usted and Ustedes)

All formal commands (both affirmative and negative) use the present subjunctive usted or ustedes forms:

• Usted (Affirmative & Negative): ¡Hable! / ¡No hable! | ¡Coma! / ¡No coma! | ¡Haga! / ¡No haga!
• Ustedes (Affirmative & Negative): ¡Hablen! / ¡No hablen! | ¡Coman! / ¡No coman! | ¡Hagan! / ¡No hagan!

First Person Plural Commands (Nosotros/as - "Let's")

• Uses the present subjunctive nosotros form: ¡Hablemos! (Let's talk!), ¡Comamos! (Let's eat!).
• Exception: The verb Ir in affirmative uses the present indicative: ¡Vamos! (Let's go!), but negative uses subjunctive: ¡No vayamos!

2. Pronoun Placement with Commands

Pronoun placement follows a rigid rule based on command polarity:

1. Affirmative Commands $\rightarrow$ ATTACH to the end of the verb:

   • Direct/Indirect object and reflexive pronouns are attached directly to the end of the verb to form a single word.
   • Written Accent Rule: If adding pronouns creates a word of 3 or more syllables, add a written accent mark to preserve the original stressed vowel.
   • Compra el libro $\rightarrow$ ¡Cómpralo! (Accent on có)
   • Da el regalo a Juan $\rightarrow$ ¡Dáselo! (Indirect pronoun le becomes se before lo)
   • Lávate las manos $\rightarrow$ ¡Lávatelas!

2. Negative Commands $\rightarrow$ PLACE BEFORE the verb as separate words:

   • Pronouns always precede the verb after no.
   • ¡No lo compres! | ¡No se lo des! | ¡No te las laves!

3. Ser vs. Estar: Advanced Contrast & Meaning Changes

Both ser and estar mean "to be," but they are not interchangeable.

Core Distinctions

• SER (DOCTOR):
  • Description / Identity (Él es alto y médico.)
  • Occupation (Ella es profesora.)
  • Characteristic (La fruta es dulce.)
  • Time / Date / Season (Hoy es lunes, son las tres.)
  • Origin / Material (El reloj es de Suiza / es de oro.)
  • Relationship / Event Location (La conferencia es en el auditorio.)
• ESTAR (PLACE):
  • Position (El libro está sobre la mesa.)
  • Location of objects/people (Juan está en España.)
  • Action (Progressive tenses: Estoy estudiando.)
  • Condition / Physical State (El café está frío.)
  • Emotion / Mental State (Ella está contenta.)

Event Location vs. Object Location

• Location of an event $\rightarrow$ SER: La fiesta es en mi casa. (The party takes place at my house.)
• Location of a physical object/person $\rightarrow$ ESTAR: Mi casa está en la calle Olmo. (My house is located on Elm Street.)

Dynamic Meaning Changes

Several adjectives drastically alter their meaning depending on whether they are paired with ser or estar:

4. Passive Constructions: True Passive vs. Passive / Impersonal "Se"

Spanish handles passive action in two primary ways:

1. True Passive Voice (Ser + Past Participle + por)

• Formula: Subject + SER + Past Participle (agrees in gender/number with subject) + por + agent.
• Use: Used in formal, journalistic, or historical contexts where the agent performing the action is emphasized.
• Examples:
  • El libro fue escrito por Gabriel García Márquez. (The book was written by Gabriel García Márquez.)
  • Las casas fueron construidas por la empresa. (The houses were built by the company.)

2. Passive and Impersonal "Se" (Se + Verb)

• Formula: Se + 3rd-person singular or plural verb + noun.
• Use: Far more common in conversational and written Spanish when the agent is unknown, general, or irrelevant.
• Examples:
  • • Se habla español aquí.* (Spanish is spoken here. [Singular verb for singular noun español])
  • • Se venden apartamentos.* (Apartments for sale / Apartments are sold. [Plural verb for plural noun apartamentos])
  • • Se prohíbe fumar.* (Smoking is prohibited.)
