Familiar Commands: Affirmative and Negative Tú Commands

Affirmative Tú Commands

  • Topic and purpose: Familiar commands are used to give orders or advice to someone you address; you start with affirmative commands.
  • Regular formation rule: A regular affirmative to command uses the él/ella form of the present indicative.
    • Formula: Affirmative tuˊ form (regular)=Present Indicative (eˊl/ella form)\text{Affirmative tú form (regular)} = \text{Present Indicative (él/ella form)}
  • Pronoun attachment in affirmative commands: In affirmative commands, reflexive, direct object, and indirect object pronouns are all attached to the end of the verb.
  • Context cue: Context will tell you which verb is being used.

Negative Tú Commands

  • AR verbs formation: For AR verbs, take the yo form of the present tense, drop the -o, and add -es.
    • Formula: Negative tuˊ, AR=(yo present)−o+ -es\text{Negative tú, AR} = (\text{yo present}) - o + \text{ -es}
  • ER and IR verbs formation: For ER and IR verbs, take the yo form of the present tense, drop -yo, and add -as.
    • Formula: Negative tuˊ, ER/IR=(yo present)−o+ -as\text{Negative tú, ER/IR} = (\text{yo present}) - o + \text{ -as}
  • Stem-changing verbs: Stem-changing verbs keep their stem changes in the negative tú commands.
  • Irregular yo present forms: Verbs that end in an irregular yo form in the present tense have the same irregularity in their negative tú commands.
  • Spelling changes with -car, -gar, -zar: Verbs that end in -car, -gar, and -zar have a spelling change in the negative tú commands.
  • Irregular negative tú commands: The following verbs have irregular negative tú commands (note: the specific verbs are listed elsewhere).
  • Pronoun placement in negative commands: In negative commands, reflexive, direct object, and indirect object pronouns come before the verb.
  • Irregulars count (from the lesson):
    • Eight irregular affirmative tú commands exist.
    • Five irregular negative tú commands exist.

Spelling-change details for negative tú commands (examples)

  • -car verbs: the spelling changes to accommodate the -qu- sound before -es (e.g., buscar -> no busques).
  • -gar verbs: the spelling changes to accommodate the -gu- sound before -es (e.g., llegar -> no llegues).
  • -zar verbs: the spelling changes to accommodate the -c- before -es (e.g., empezar -> no empieces).

Pronouns and word order specifics

  • Affirmative commands: pronouns (reflexive, direct, indirect) attach to the end of the verb.
  • Negative commands: pronouns come before the verb (before the conjugated verb form).
  • The base verb form used for these constructions comes from the present tense, with irregularities and spelling changes applied as described above.

Quick connections and implications

  • Practical use: These rules are essential for giving informal commands or advice in everyday Spanish.
  • Contextual cues: Verb choice and whether the command is affirmative or negative determine the exact form.
  • Real-world relevance: Mastery of these forms enables clear, direct communication in casual settings and aligns with the broader imperative mood in Spanish.

Summary of key rules

  • Affirmative tú commands: use the él/ella form of the present indicative; attach pronouns to the end.
    • Formula: Affirmative tuˊ form=Present Indicative (eˊl/ella)\text{Affirmative tú form} = \text{Present Indicative (él/ella)}
  • Negative tú commands: from the yo present form, drop -o and add -es for AR or -as for ER/IR; stem changes persist; irregular yo forms carry over; -car/-gar/-zar have spelling changes; pronouns precede the verb.
    • Formulas: Negative tuˊ, AR=(yo present)−o+−es\text{Negative tú, AR} = (\text{yo present}) - o + -es
    • Negative tuˊ, ER/IR=(yo present)−o+−as\text{Negative tú, ER/IR} = (\text{yo present}) - o + -as
  • Eight irregular affirmative tú commands; five irregular negative tú commands.
