What are verb signals and why they matter
Verb signals are words or expressions that indicate tense, mood, or whether you should use an infinitive, present, past, or subjunctive form. Recognizing these signals helps you form correct questions and understand answers. For beginners, mastering a handful of common signals speeds comprehension and speaking confidence.
Basic categories of verb signals
There are several useful categories: time markers (now, yesterday), modal signals (can, must), question words (who, what), and expressions that require the infinitive or subjunctive. Learn one category at a time and practice with short examples.
Common question words and their verb signals
Spanish question words guide which verb forms are typical in questions. Here are the most useful ones for beginners.
¿Qué? — what
Use with: present, past, or infinitive
Examples:
¿Qué quieres?
Explain: Use present when asking for current wants. quiere is third person; quieres is you informal.
¿Qué hiciste ayer?
Explain: Use preterite with time signal ayer (yesterday).
¿Qué hacer ahora?
Explain: Use infinitive for instructions or signs, like on a form or manual.
¿Quién? — who
Use with: present or past depending on time reference
Examples:
¿Quién viene?
Explain: Use present for people arriving now.
¿Quién llamó?
Explain: Use preterite to ask who called earlier.
¿Cuándo? — when
Use with: future, present, past
Examples:
¿Cuándo empieza la clase?
Explain: Use present for scheduled events (starts).
¿Cuándo llegaste?
Explain: Preterite for specific past arrival.
¿Dónde? — where
Use with: estar, ir, quedar
Examples:
¿Dónde está el baño?
Explain: Use estar for locations.
¿Dónde ponemos las maletas?
Explain: Use present if deciding now.
¿Por qué? — why
Use with: porque explanations, subjunctive in certain structures
Examples:
¿Por qué no vienes?
Explain: Present negative question; answer often starts with porque.
¿Por qué dudas que ella venga?
Explain: Subjunctive venga after verb of doubt (dudar).
Signals that call for the infinitive
Several short expressions require an infinitive rather than a conjugated verb. These are very common on signs, menus, instructions, and when making polite requests.
Para — to/for (purpose)
Use with infinitive to express purpose.
Examples:
Para entrar, mostrar identificación.
Explain: Instruction on a sign meaning to enter, show ID. Use infinitive entrar and mostrar.
Antes de / después de — before / after
Use with infinitive when no change of subject.
Examples:
Antes de comer, lávate las manos.
Después de hacer ejercicio, descansa.
Explain: These set the order of actions; infinitives follow.
Sin — without
Use with infinitive to express doing something without another action.
Examples:
No salgas sin llamar.
Explain: Use infinitive llamar after sin.
Signals that often require the subjunctive in questions
The subjunctive appears after expressions that express doubt, desire, emotion, or impersonal recommendations. Beginners should learn the most frequent signals that trigger this mood.
Quiero que — I want that (someone does something)
Use with subjunctive when asking about wishes.
Examples:
¿Quieres que yo vaya?
Explain: Use vaya (subjunctive) after quieres que to ask if someone wants you to go.
Es importante que — It is important that
Use with subjunctive to express necessity or recommendation.
Examples:
¿Es importante que lleguemos a tiempo?
Explain: lleguemos is subjunctive because the phrase expresses importance.
Dudo que — I doubt that
Use with subjunctive after verbs of doubt or disbelief.
Examples:
¿Dudas que él tenga la llave?
Explain: tenga is subjunctive after dudar.
Time markers and tense signals for questions
Time words often determine tense. Recognize these signals to choose present, preterite, imperfect, or future when asking questions.
Ahora — now
Signal for present or present progressive.
Examples:
¿Ahora trabajas?
¿Ahora estás trabajando?
Explain: Use present or present progressive to ask about current action.
Ayer / anoche — yesterday / last night
Signal for preterite.
Examples:
¿Ayer fuiste al mercado?
¿Anoche viste la película?
Explain: Use preterite fuiste, viste for completed past actions.
Mañana — tomorrow
Signal for future, present for scheduled events, or ir a + infinitive.
Examples:
¿Mañana vienes?
¿Mañana vas a salir?
Explain: Use present for scheduled plans or ir a + infinitive for near future.
Practical beginner tips: recognizing signals in context
Tip 1: Scan for short signal words first. Words like antes de, después de, ahora, ayer, and question words appear often and quickly tell you which verb form to use.
Tip 2: Match subjects to verbs. If the subject changes after a preposition like para or antes de, you may need a conjugated verb instead of an infinitive. Example, compare:
Antes de salir (same subject)
Antes de que salga (different subject — requires subjunctive)
Explain: The signal antes de que introduces subjunctive when subjects differ.
Tip 3: Watch verbs of desire, doubt, emotion. Verbs like querer, dudar, esperar often signal the subjunctive. If a question asks about wishes or doubts, expect subjunctive after que.
Tip 4: For polite requests, use the infinitive or conditional basics. Examples you might hear or read:
Por favor, mostrar identificación
¿Puedes ayudarme?
Explain: Signs and forms often use infinitives; spoken politeness uses puedes + infinitive or conditional forms.
Common beginner mistakes and how to avoid them
Mistake 1: Using infinitive when a conjugated verb is needed. Avoid by checking whether the subject changes after the signal. If the subject stays the same, infinitive is OK. If it changes, conjugate the verb and consider subjunctive if required.
Example error:
Antes de que yo salir.
Correction:
Antes de que yo salga.
Mistake 2: Confusing preterite and imperfect after time signals. Use preterite for completed single events with words like ayer. Use imperfect for ongoing past actions or background.
Examples:
¿Ayer comiste pizza?
¿Cuando eras niño, ibas a la playa a menudo?
Mistake 3: Not using subjunctive after expressions of emotion or doubt. Practice common patterns like querer que, esperar que, dudar que followed by subjunctive.
Examples:
¿Esperas que él venga?
¿Dudas que ellos lleguen a tiempo?
