Mastering Spanish Verbs: Tenses, Moods, and Conjugation
Welcome to your comprehensive revision guide for Spanish Verbs, tailored specifically for the CCEA AS Level specification. Whether you are aiming for top marks in your Unit AS 2 grammatical transformation tasks or working to improve the accuracy and variety of your writing in Unit AS 3, verbs form the backbone of your success.
Don't worry if verb conjugations feel overwhelming at first. Spanish verb systems follow clear patterns. Once you learn the structures, triggers, and key exceptions, you will be able to construct accurate, sophisticated sentences across all your AS themes (Relationships, Culture and Lifestyle, and Young People in Society).
---1. The Present Tense (El Presente) & Core Classifications
The present tense is used to describe current actions, habitual habits, and universal truths. Before looking at more complex tenses, let's make sure our foundation is completely secure.
Regular Present Tense Endings
To conjugate regular verbs, remove the infinitive ending (-ar, -er, or -ir) and add the appropriate endings:
• -AR Verbs (e.g., hablar): -o, -as, -a, -amos, -áis, -an
• -ER Verbs (e.g., comer): -o, -es, -e, -emos, -éis, -en
• -IR Verbs (e.g., vivir): -o, -es, -e, -imos, -ís, -en
High-Frequency Irregular Verbs
You must know these essential irregular verbs automatically:
• Ser (to be): soy, eres, es, somos, sois, son
• Estar (to be): estoy, estás, está, estamos, estáis, están
• Ir (to go): voy, vas, va, vamos, vais, van
• Tener (to have): tengo, tienes, tiene, tenemos, tenéis, tienen
• Hacer (to do/make): hago, haces, hace, hacemos, hacéis, hacen
Radical-Changing (Stem-Changing) Verbs
Some verbs undergo a vowel change in the stem for all persons except nosotros and vosotros (the "boot" rule):
• e > ie: pensar (to think) → pienso, piensas, piensa, pensamos, pensáis, piensan
• o > ue: poder (to be able to) → puedo, puedes, puede, podemos, podéis, pueden
• e > i: pedir (to ask for) → pido, pides, pide, pedimos, pedís, piden
Crucial Distinction: Ser vs. Estar
Both mean "to be", but they cannot be used interchangeably:
• Ser: Used for permanent traits, identity, nationality, profession, and origin. (e.g., Mi hermano es sociable - My brother is sociable).
• Estar: Used for temporary states, emotions, conditions, and physical location. (e.g., Estoy cansado hoy - I am tired today; Belfast está en Irlanda del Norte - Belfast is in Northern Ireland).
Reflexive Verbs and Pronoun Placement
Reflexive verbs use pronouns: me, te, se, nos, os, se.
• Before a conjugated verb: Me levanto temprano (I get up early).
• Attached to an infinitive: Voy a levantarme (I am going to get up).
• Attached to a gerund: Estoy levantándome (I am getting up).
Key Takeaway: Lock down regular endings first, remember the "boot" rule for radical changes, and always double-check whether a description needs ser (inherent trait) or estar (temporary state/location).
---2. Mastering the Past Tenses: Preterite, Imperfect, and Compounds
Past tense selection is one of the most heavily assessed areas at AS Level. CCEA examiners look specifically for your ability to alternate smoothly between the Preterite and the Imperfect.
A. The Preterite (El Pretérito Indefinido)
The preterite is used for completed actions at a specific point in the past (actions with a clear beginning and end).
Regular Endings:
• -AR: -é, -aste, -ó, -amos, -asteis, -aron (e.g., hablé, hablaste, habló...)
• -ER / -IR: -í, -iste, -ió, -imos, -isteis, -ieron (e.g., comí, comiste, comió...)
Common Irregular Preterites (Examiner Watchpoint!):
Many common irregular verbs take a new stem and use the endings -e, -iste, -o, -imos, -isteis, -ieron (with no written accents):
• Hacer → stem hic-: hice, hiciste, hizo, hicimos, hicisteis, hicieron (Note the z in hizo — avoid writing hició!)
• Poder → stem pud-: pude, pudiste, pudo, pudimos, pudisteis, pudieron (Avoid writing puedió!)
• Tener → stem tuv-: tuve, tuviste, tuvo, tuvimos, tuvisteis, tuvieron
• Ir / Ser (identical in preterite): fui, fuiste, fue, fuimos, fuisteis, fueron
B. The Imperfect (El Pretérito Imperfecto)
The imperfect is used for habitual actions ("used to" or "would" in the past), ongoing descriptions, background settings, and age or time in the past.
Regular Endings:
• -AR: -aba, -abas, -aba, -ábamos, -abais, -aban
• -ER / -IR: -ía, -ías, -ía, -íamos, -íais, -ían
The Only Three Irregular Imperfect Verbs:
• Ir: iba, ibas, iba, íbamos, ibais, iban
• Ser: era, eras, era, éramos, erais, eran
• Ver: veía, veías, veía, veíamos, veíais, veían
Preterite vs. Imperfect: How to Alternate
Think of the past as a movie scene:
• The Imperfect sets the scene (the background, weather, emotions, what was already happening).
• The Preterite is the action that occurs (an event that interrupts or happens at a specific moment).
Example: Hacía sol y la gente paseaba (Imperfect - background) cuando de repente empezó a llover (Preterite - specific event).
C. The Perfect Tense (El Pretérito Perfecto)
Used for actions that happened recently or in a time period that is still continuing (e.g., today, this week, this year).
Formula: Present tense of Haber + Past Participle
• Haber: he, has, ha, hemos, habéis, han
• Past Participle: -ar → -ado (hablado); -er/-ir → -ido (comido, vivido)
Example: Hoy he hablado con mis padres sobre mis estudios. (Today I have spoken with my parents about my studies.)
D. The Pluperfect Tense (El Pretérito Pluscuamperfecto)
Used to describe an action that happened before another past action ("had done").
Formula: Imperfect tense of Haber + Past Participle
• Haber: había, habías, había, habíamos, habíais, habían
• Past Participle: -ado / -ido
Example: Cuando llegué a la fiesta, Juan ya se había ido. (When I arrived at the party, Juan had already left.)
Major Pitfall: Haber vs. Tener
Never use tener to form compound tenses! Haber is the only auxiliary verb for compound past tenses. Tener is used solely to express physical possession or obligation (tener que + infinitive).
Key Takeaway: Use the Imperfect for continuous background and habits, the Preterite for completed actions, and Haber (never tener) with a past participle for compound tenses.
---3. Future and Conditional Tenses
A. The Near Future (Futuro Próximo)
Used widely in spoken and written Spanish for plans and immediate future events.
Formula: ir (in present) + a + infinitive
Example: El año que viene voy a estudiar en la universidad. (Next year I am going to study at university.)
B. The Simple Future (Futuro Simple)
Used for future predictions, promises, or formal statements. The endings are attached directly to the full infinitive for regular verbs:
Endings (all verb types -ar, -er, -ir): -é, -ás, -á, -emos, -éis, -án
• Hablar → hablaré, hablarás, hablará, hablaremos, hablaréis, hablarán
• Comer → comeré, comerás...
• Vivir → viviré, vivirás...
C. The Conditional (Condicional)
Used for hypothetical scenarios ("would do"), giving advice, or polite requests. Like the simple future, endings are added to the infinitive:
Endings (all verb types -ar, -er, -ir): -ía, -ías, -ía, -íamos, -íais, -ían
• Hablar → hablaría, hablarías, hablaría, hablaríamos, hablaríais, hablarían
• Comer → comería, comerías, comería, comeríamos, comeríais, comerían
Example: Si tuviera más tiempo libre, haría más deporte. (If I had more free time, I would do more sport.)
Key Takeaway: Both the Simple Future and Conditional use the entire infinitive as the base for regular verbs. Notice how future endings have accents on almost all vowels (-é, -ás, -á, -án) and conditional endings match regular -er/-ir imperfect endings (-ía...).
---4. The Present Subjunctive Mood (El Presente de Subjuntivo)
The subjunctive is a mood, not a tense. It is used to express subjectivity, doubt, emotion, purpose, or necessity. Demonstrating accurate use of the present subjunctive is vital for securing higher-tier marks in CCEA AS Level writing and grammar tasks.
How to Form the Present Subjunctive
Follow this three-step recipe for regular verbs:
1. Take the yo form of the present indicative (e.g., hablo, como, vivo).
2. Drop the -o ending to find the stem (e.g., habl-, com-, viv-).
3. Add the opposite vowel endings:
• -AR Verbs (take "e" endings): -e, -es, -e, -emos, -éis, -en (e.g., hable, hables, hable, hablemos, habléis, hablen)
• -ER / -IR Verbs (take "a" endings): -a, -as, -a, -amos, -áis, -an (e.g., coma, comas, coma, comamos, comáis, coman; viva, vivas, viva...)
CCEA Required Triggers for the Subjunctive
You must know the key triggers required by the CCEA specification:
1. Verbs of Emotion, Desire, and Influence
When you want, hope, or fear someone else will do something:
• Espero que (I hope that)... → Espero que vengas a mi fiesta.
• Quiero que (I want that)... → Mis padres quieren que estudie más.
2. Impersonal Expressions
Phrases expressing value judgments or necessity:
• Es importante que... → Es importante que los jóvenes hagan ejercicio.
• Es necesario que... → Es necesario que protejamos el medio ambiente.
• Es una lástima que... → Es una lástima que haya tanta contaminación.
3. Conjunctions of Time and Purpose
• Para que (so that / in order that): Always triggers the subjunctive! → Trabajo duro para que mis padres estén orgullosos.
• Cuando + future reference: When cuando introduces an event that has not happened yet, use the subjunctive → Cuando sea mayor, viviré en España. (When I am older [in the future], I will live in Spain).
Crucial Subjunctive Rule: The Subject Must Change!
If there is no change of subject, do not use the subjunctive; use an infinitive instead:
• Same subject: Quiero salir (I want to go out — both actions refer to "I").
• Different subjects: Quiero que salgas (I want you to go out — Subject 1 is "I", Subject 2 is "you").
Key Takeaway: Flip the vowel (-ar → e, -er/-ir → a), check for your trigger phrase, and verify that there is a change of subject before writing the subjunctive!
---5. Imperatives, Gerunds, and Participles
A. The Imperative (Commands)
Used to give orders, advice, or instructions:
• Affirmative Tú (Familiar singular): Use the third-person singular (él/ella) form of the present indicative → ¡Habla! (Speak!), ¡Come! (Eat!).
• Negative Tú: Use the tú form of the present subjunctive → ¡No hables! (Don't speak!), ¡No comas! (Don't eat!).
• Usted / Ustedes (Polite): Use the third-person singular/plural forms of the present subjunctive → ¡Hable usted! / ¡No fumen ustedes!
B. Gerunds (El Gerundio) and Continuous Tenses
Formed with -ando for -ar verbs and -iendo for -er/-ir verbs.
• Used with estar to form continuous actions happening right now: Estoy hablando con mi amigo (I am talking with my friend).
• Irregular gerunds to remember: leer → leyendo, dormir → durmiendo, decir → diciendo.
Anglicism Alert (Examiner-Reported Mistake):
Do not translate the English structure "I have been living here for 5 years" directly with a continuous tense (Estoy viviendo...). In Spanish, express ongoing time with:
• Desde hace + time: Vivo en Belfast desde hace cinco años.
• Llevar + time + gerund: Llevo cinco años viviendo en Belfast.
C. Past Participles (El Participio)
• Regular forms: -ado (for -ar) and -ido (for -er/-ir).
• Used in compound tenses with haber (remains invariable: Ellas han hablado).
• Used as adjectives (must agree in gender and number: Las puertas están cerradas — The doors are closed).
6. Top CCEA Exam Checklist & Common Pitfalls
Before submitting your Unit AS 2 grammar exercises or Unit AS 3 essays, run through this quick checklist:
1. Preterite vs Imperfect alternation: Did you use the imperfect for the ongoing background/description and the preterite for the specific, completed action?
2. Compound Tenses: Have you used haber (and never tener) alongside the past participle?
3. Irregular Preterite Check: Did you double-check tricky stems like hizo (not hició) and pudo (not puedió)?
4. Subjunctive Subject Check: Is there an actual change of subject? Remember: Espero aprobar (I hope to pass) vs. Espero que apruebes (I hope that you pass).
5. Time Expressions: Did you use desde hace or llevar + gerund instead of a direct English continuous translation?
