Using prepositions in Spanish: Complete guide with rules and exceptions

Prepositions are small words that play a crucial role in sentence structure, allowing relationships to be established between different elements. Although they may seem simple, their correct use can challenge both native speakers and Spanish learners. Prepositions can indicate location, time, cause, and belonging, among other things, and their misuse can alter the meaning of a sentence. In this article, we will explore the basic rules for using prepositions in Spanish and the exceptions and exceptional cases that often confuse.

What are prepositions?

Prepositions are invariable words that introduce complements and connect different elements within a sentence. For example, in the sentence: Voy a la tienda (I’m going to the store), the preposition a connects the verb voy with the place la tienda, indicating direction. Some of the most common prepositions in Spanish include a, de, en, con, por, para, sin, sobre, and desde, among others.

Basic rules for the use of prepositions

1. Using “a” to indicate direction or movement:

The preposition “a” expresses movement or direction toward a place or a goal. It is essential to let you know a destination.

• Example: “Voy a la universidad” (I’m going to university) (direction).
• Example: “Llamé a mi madre” (I called my mother) (goal or recipient).

An essential rule with a is that it is also used before direct objects when they are people, known as the “personal a”.

• Example: “Vi a Juan en el parque” (I saw Juan in the park).

This rule is omitted when the direct object is not a person:  “Vi el perro” (I saw the dog).

2. “De” to indicate belonging, origin or cause

The preposition ‘de’ is a versatile tool in Spanish grammar. Its applications range from expressing possession and origin to indicating matter, among other uses. Its broad applicability will enhance your understanding of the language.

• Example: “Este libro es de María” (This book is Maria’s) (belonging).
• Example:  “Soy de España” (I am from Spain) (origin).
• Example: “La mesa es de madera” (The table is made of wood) (material).

It is important not to confuse the use of “de” with “desde” since the latter indicates a starting point in space or time: “El tren salió desde la estación” (The train left from the station).

3. “En” to indicate location or time

The preposition “en” generally indicates location or time. Unlike “a,” which implies movement, “en” means something or someone is in a specific place without indicating displacement.

• Example: “Estoy en casa” (location).
• Example: “Nos vemos en enero” (time).

An interesting exception is that “en” is not always used for transportation since we say: “Voy a pie” (not “en pie”).

4. “Por” and “para”: a typical case of confusion

These two prepositions often need clarification because, in some contexts, they have similar meanings in other languages, such as English. However, in Spanish, they have particular uses:

• “Por” is used to express cause, means, duration or exchange.
• Example: “Lo hago por ti” (I do it for you) (cause).
• Example: “Viajo por tren” (I travel by train) (means).
• Example: “Estudié por tres horas” (I studied for three hours) (duration).
• “Para” indicates destination, purpose or recipient.
• Example: “Este regalo es para ti” (This gift is for you) (recipient).
• Example:  “Trabajo para ganar dinero” (I work to earn money) (purpose).

5. “Con” for company or instrument

The preposition “con” indicates company or how an action is carried out.

• Example: “Fui al cine con mis amigos” (I went to the movies with my friends) (company).
• Example:  “Corto el pan con un cuchillo” (I cut bread with a knife) (instrument).

It’s important to note that there are exceptions to the use of ‘con ‘. In verbal expressions such as  soñar con (dream about) or enamorarse de (fall in love with), the meaning does not indicate company but rather an idiomatic construction. Understanding these exceptions can be a challenging yet engaging part of learning the Spanish language.

Exceptions and special cases

Prepositions in Spanish, although they follow explicit rules, also present exceptional cases that must be memorised:

• “A” + infinitive: The preposition “a” can be followed by an infinitive to indicate an imminent purpose or action: “Voy a estudiar.”
• “De” + infinitive: In expressions like “acabar de + infinitivo,” an action that has just happened is expressed: “Acabo de llegar.”
• Verbs with a fixed preposition: Some verbs in Spanish always require a specific preposition. For example:

• “Depender de”.
• “Soñar con”.
• “Consistir en”.

Using the wrong preposition in these cases alters the meaning or results in a grammatical error.

Tips to avoid common mistakes

1. Memorize the prepositions that accompany certain verbs: Some verbs always require a specific preposition, such as “fall in love with” or “think about.” Learning these cases is crucial in avoiding mistakes.

• Context is key: The meaning of a preposition can shift depending on the context. For instance, “por” can denote cause (“Lo hice por ti”/ ”I did it for you”) or means (“Hablé por teléfono”/ “I spoke on the phone”). Understanding these nuances will boost your confidence in using prepositions correctly.

• Beware of literal translations: Not all prepositions have a direct counterpart in another language. For instance, in English, we say “think about,” but in Spanish, it’s “pensar en.” Being mindful of these differences will enhance your language skills.

Correct use of prepositions is essential for clarity and precision in Spanish. Although they may seem difficult due to the numerous rules and exceptions, with practice and attention, they can be mastered. Remembering the basic rules, memorising the exceptions, and observing the context in which they are used can help you avoid common mistakes and improve your fluency in Spanish.
