Spanish 4 Comprehensive Grammar Review

The Present Indicative (The Foundation)

This tense serves as the bedrock of the language, and proficiency requires the ability to use these forms instantly without conscious thought.

• Regular Verbs: Conjugation follows specific patterns based on the infinitive ending:

  • -ar Verbs: The endings are $-o$, $-as$, $-a$, $-amos$, $-áis$, and $-an$.

  • -er Verbs: The endings are $-o$, $-es$, $-e$, $-emos$, $-éis$, and $-en$.

  • -ir Verbs: The endings are $-o$, $-es$, $-e$, $-imos$, $-ís$, and $-en$.

• High-Frequency Irregulars: Several essential verbs do not follow regular patterns and must be memorized: Ser, estar, ir, tener, hacer, poner, salir, venir, decir, oír, traer, saber, and conocer.

• Stem-Changers (Shoe Verbs): These verbs undergo a vowel change in the stem in all forms except for nosotros and vosotros. Common patterns include:

  • e → ie: For example, pensar.

  • o → ue: For example, poder.

  • e → i: For example, pedir.

• "Yo-Go" Verbs: These verbs feature an irregular first-person singular (yo) form ending in -go, though other forms may be regular or stem-changing. Examples include:

  • Tengo (from tener)

  • Hago (from hacer)

  • Pongo (from poner)

  • Salgo (from salir)

  • Traigo (from traer)

  • Digo (from decir)

The Two Past Tenses (Preterite vs. Imperfect)

Advanced Spanish study requires distinguishing between the two past tenses based on the specific context of the action.

• Preterite (Specific, Completed Actions): Used for actions that are viewed as finished or occurred at a specific point in time.

  • Regular -ar endings: $é$, $aste$, $ó$, $amos$, $asteis$, $aron$.

  • Regular -er/-ir endings: $í$, $iste$, $ió$, $imos$, $isteis$, $ieron$.

  • Irregular Stems (The "U-v-i-j" Groups): These use specific irregular stems: tuve, estuve, pude, supe, hice, quise, vine, dije, and traje.

  • Car, Gar, Zar Verbs: These require spelling changes in the yo form only to preserve pronunciation: buscar becomes busqué, pagar becomes pagué, and empezar becomes empecé.

  • Sole Verbs: These are stem-changers that only occur in the $3rd$-person forms (singular and plural). Examples include durmió and pidió.

• Imperfect (Descriptions, Habits, Background Information): Used for ongoing actions, repeated habits, or providing descriptive context in the past.

  • Regular -ar endings: $aba$, $abas$, $aba$, $ábamos$, $abais$, $aban$.

  • Regular -er/-ir endings: $ía$, $ías$, $ía$, $íamos$, $íais$, $ían$.

  • Only Three Irregulars: There are only three irregular verbs in the imperfect: Ser ($era$), Ir ($iba$), and Ver ($veía$).

The Future and Conditional Tenses

These are considered the simplest tenses to conjugate because the endings are attached directly to the full infinitive of the verb.

• Future Tense (What will happen): The endings added to the infinitive are $é$, $ás$, $á$, $emos$, $éis$, and $án$.

• Conditional Tense (What would happen): The endings added to the infinitive are $ía$, $ías$, $ía$, $íamos$, $íais$, and $ían$.

• Irregular Stems: Both the future and conditional tenses share the same $12$ irregular stems. The provided stems include:

  • tendr-

  • sabr-

  • podr-

  • pondr-

  • saldr-

  • har-

  • dir-

  • vendr-

Perfect Tenses (Compound Verbs)

Perfect tenses are compound forms created by combining the auxiliary verb Haber with a Past Participle.

• Past Participle Formation: Regular past participles end in $-ado$ (for -ar verbs) or $-ido$ (for -er and -ir verbs). Irregular past participles include:

  • hecho

  • escrito

  • visto

  • abierto

  • dicho

• Present Perfect (Have done): Used for actions that have occurred. It uses the present tense of Haber:

  • $he, has, ha, hemos, habéis, han$

• Past Perfect / Pluperfect (Had done): Used for actions that had occurred before another past action. It uses the imperfect tense of Haber:

  • $había, habías, había, habíamos, habíais, habían$

The Subjunctive Mood

The subjunctive mood represents the core of advanced Spanish study. It marks a shift from communicating facts (Indicative) to expressing doubt, emotion, wishes, and things that are unknown.

• Present Subjunctive Formation:

  1. Start with the yo form of the present indicative.

  2. Drop the $-o$ ending.

  3. Add the opposite endings: -ar verbs receive -er endings, while -er and -ir verbs receive -ar endings.

• WEIRDOS Trigger Acronym: The subjunctive is only utilized if a sentence contains two different subjects joined by a relative pronoun (que) and includes a trigger following the WEIRDOS categories:

  • W: Wish

  • E: Emotion

  • I: Impersonal expression

  • R: Recommendation

  • D: Doubt

  • O: Obligation

Commands (Imperatives)

• Formal Commands (Usted/Ustedes): These forms use the present subjunctive endings. Examples include Hable! or No hable!.

• Informal Affirmative Commands (Tú): These use the regular $3rd$-person singular form of the present indicative. For example: Habla!.

• Informal Negative Commands (Tú): These use the tú form of the present subjunctive. For example: No hables!.

Pronoun Placement

• Identification of Pronouns:

  • Direct Objects: Me, te, lo/la, nos, os, los/las.

  • Indirect Objects: Me, te, le, nos, os, les.

• The "La-La" Rule: In Spanish, it is grammatically incorrect to use le or les immediately before lo, la, los, or las. In these instances, le and les must change to se. For example, Se lo di (I gave it to him) instead of le lo di.

• Placement Rules: Pronouns are placed according to the following structures:

  • Before a conjugated verb.

  • Attached to the end of an infinitive.

  • Attached to the end of a gerund.

  • Attached to the end of an affirmative command.
