Master Spanish A-Level Grammar: Essential Notes

Active vs Passive Voice

Active voice is straightforward - the subject does the action directly. Think "The team built the house" (El equipo construyó la casa). The doer comes first, then the action, then what receives the action.

Passive voice flips this around - the thing being acted upon becomes the focus. "The house was built by the team" (La casa fue construida por el equipo). Notice how you use "fue" (was) plus the past participle, followed by "por" to show who did the action.

Quick tip: Active voice sounds more natural in everyday conversation, whilst passive voice is often used in formal writing or when you want to emphasise what happened rather than who did it.

The key difference is where you put your focus - on the person doing something (active) or on what's being done to something (passive).

Reflexive Constructions

Reflexive as passive uses "se" to talk about general actions without naming who does them. "Se vende pescado" means "fish is sold" - you're not specifying who sells it. This construction only works with things, not people.

Reflexive as impersonal makes general statements when there's no clear subject. It's always conjugated in third person singular, so you'd say "Se habla español" (Spanish is spoken) rather than trying to identify specific speakers.

Remember: Always use SE + verb in 3rd person singular + complement for these constructions.

This might feel weird at first, but it's incredibly useful for describing general situations or common practices without getting bogged down in specifics.

Verb Conjugation Chart

Spanish verbs follow predictable patterns once you learn the endings. Present tense uses endings like -o, -as, -a for regular verbs. Preterite (completed past actions) adds endings like -é, -aste, -ó.

Imperfect tense describes ongoing past actions with -aba/-ía endings. Future tense simply adds -é, -ás, -á to the infinitive - dead easy!

Perfect tenses combine "haber" (have) with past participles ending in -ado or -ido. Conditional expresses "would" situations using -ía endings added to the infinitive.

Study hack: Focus on learning one tense thoroughly before moving to the next - don't try to memorise everything at once!

These patterns repeat across thousands of verbs, so mastering these endings gives you massive vocabulary power.

Ser vs Estar - The Ultimate Guide

Both ser and estar mean "to be," but they're used in completely different situations. Ser describes permanent characteristics, occupations, origin, and inherent qualities. Think of things that don't change easily.

Estar focuses on temporary states, locations, emotions, and conditions. The golden rule: use estar for how you feel and where you are right now.

"Soy inteligente" (I am intelligent - permanent trait) versus "Estoy cansado" (I am tired - temporary state). "María es de España" (origin) versus "María está en España" (current location).

Memory trick: Remember "HOW you FEEL, WHERE you ARE - that's when you use ESTAR!"

Don't worry if you mix these up initially - even advanced learners sometimes pause to think about which one to use!

When to Use Ser

Ser handles descriptions that define someone or something permanently. Use it for professions (without articles): "Pilar es médica" - no "una" needed before the job title.

Origin and possession always take ser: "Soy de Estados Unidos" or "La carta es de Felipe." Physical and personality traits that don't change also use ser: nationalities, colours, and character descriptions.

Time expressions rely heavily on ser: "¿Qué hora es?" (What time is it?), "Es miércoles" (It's Wednesday), and "¿Cuál es la fecha?" (What's the date?).

Key insight: If you're describing what someone IS rather than how they feel or where they are, you probably need ser.

Think of ser as the verb for fundamental, unchanging facts about people, places, and things.

Spanish Numbers 1-1000

Basic numbers from 1-15 are unique and must be memorised: uno, dos, tres, cuatro, cinco, seis, siete, ocho, nueve, diez, once, doce, trece, catorce, quince.

Teens and twenties follow patterns: dieciséis (16), diecisiete (17), but then veinte (20), veintiuno (21), veintidós (22). After 30, you use "y" to connect: treinta y uno (31).

Hundreds change form: cien (100), but ciento uno (101). Special forms include doscientos (200), trescientos (300), quinientos (500), setecientos (700), novecientos (900).

Practice tip: Count everyday objects around you - it's the fastest way to make numbers automatic!

Once you've got the patterns down, you can count to any number by combining these building blocks.

Advanced Numbers and Years

Large numbers follow logical patterns: mil (1000), dos mil (2000), un millón (1,000,000). Years are straightforward: 2023 = "dos mil veintitrés."

Historical years use the full number: 1993 = "mil novecientos noventa y tres." No shortcuts here - you say every part of the number.

The rule-breakers you've seen (quinientos, setecientos, novecientos) apply to any number containing these hundreds, so 715 = "setecientos quince."

Real-world application: Practice with current year, your age, prices, and phone numbers - these come up constantly in conversation!

Don't stress about perfection - even native speakers sometimes stumble over long numbers, so focus on clarity over speed.

Preposition A - Multiple Uses

Motion and direction represent the most common use of "a": "ir a la ciudad" (go to the city) or "regresar a casa" (return home). It shows where you're heading.

Time expressions rely heavily on a: "a las dos" (at two o'clock), "a mediodía" (at noon), "al final" (at the end). It pinpoints when something happens.

Personal a marks human direct objects: "ver a Consuelo" (to see Consuelo). This doesn't exist in English but it's crucial in Spanish - you must use it before people's names or human nouns.

Common mistake: Forgetting personal a is a dead giveaway that you're not a native speaker - make it automatic!

Rate and manner expressions use a as well: "a pie" (on foot), "a caballo" (on horseback), "paso a paso" (step by step).

Preposition De - Essential Uses

Origin and possession are de's bread and butter: "Soy de Venezuela" (I'm from Venezuela) or "la casa de mis tíos" (my uncles' house). It shows where something comes from or who owns it.

Material and content descriptions use de: "una casa de ladrillos" (a brick house), "un vaso de agua" (a glass of water). It tells you what something's made of or contains.

Descriptive phrases often need de: "vestido de negro" (dressed in black), "lleno de agua" (full of water). These work like English "with" or "in."

Pattern recognition: When you see two nouns together in English (like "music lesson"), Spanish usually connects them with de: "lección de música."

Cause and manner expressions show why or how: "saltar de alegría" (jump for joy), "ponerse de pie" (stand up).

More Uses of De

Characteristic descriptions help identify people or things: "la mujer del sombrero rojo" (the woman with the red hat), "una persona de dinero" (a wealthy person). These phrases act like adjectives.

Time expressions with de appear in fixed phrases: "trabajar de día" (work during the day), "muy de mañana" (very early in the morning). These are set expressions you need to memorise.

Compound nouns in Spanish often use de where English puts two nouns together: "máquina de lavar" (washing machine), "cuarto de baño" (bathroom).

Translation trap: Don't translate word-for-word from English - Spanish structure with de often sounds more natural than direct translations.

Humorous or emphatic descriptions use de for effect: "el loco de Pedro" (that crazy Pedro), "la muy tonta de Marta" (silly Marta). These add emotional colour to descriptions.
