Why prepositions after communication verbs matter
In English we often use a direct object or a preposition after communication verbs, for example tell someone about something. Spanish has its own patterns. Choosing the wrong preposition can change meaning or sound unnatural. Mastering these patterns improves fluency and comprehension.
Basic distinction: direct objects vs prepositions
Some Spanish communication verbs take a direct object without a preposition: decir algo, contar una historia. Others require a preposition to introduce a person or a topic: preguntar a alguien, hablar de algo. Recognizing whether a verb needs a preposition is the first step.
Common verbs that use direct objects (no preposition)
These verbs typically follow the pattern: verb + direct object. The person or thing is expressed directly after the verb.
decir + algo / a alguien in certain uses: decir la verdad; but if you include the person explicitly you usually add the preposition a: decir la verdad a María. When the person is a pronoun, use me / te / le after the verb: le dije.
contar + algo / a alguien: contar una historia; contar a sus amigos. For personal pronouns use me, te, le, nos, os, les: nos contó la historia.
explicar + algo / a alguien: explicar la lección; explicar a los alumnos. Pronoun use: les expliqué el concepto.
Examples
Él dijo la verdad.
Le dije la hora.
Nos contó un secreto.
Verbs that require the preposition a to introduce people
The preposition a is commonly used to mark the indirect object when referring to people. Many communication verbs use a before the person receiving the information or action.
preguntar a alguien: ask someone. Use a to indicate who is being asked.
decir a alguien: say to someone. As mentioned, decir can appear without a when the person is not explicit, but to specify a listener use a.
contestar a alguien: answer someone. While contestar can be transitive, using a before the person is common: contestó a su profesor.
Examples
Voy a preguntar a Pedro mañana.
Ella dijo a los niños que era hora de cenar.
Contestó a todas las preguntas del examen.
Verbs that use the preposition de to introduce topics
The preposition de is used to introduce the subject matter or topic of communication. When you talk about what is being said or asked, de is the normal choice.
hablar de algo: talk about something. Use de to introduce the topic: hablar de política, hablar de cine.
preguntar sobre / preguntar por: while preguntar often uses a for the person, to ask about a topic you can use sobre or por. Both are possible but have nuance: preguntar sobre is more neutral, preguntar por can imply inquiring after or seeking information about.
informar de / informar sobre: used to express what is reported or informed. Informar de un cambio, informar sobre los resultados.
Examples
Hablamos de nuestras vacaciones.
Le pregunté sobre su trabajo.
El periodista informó de los resultados.
Verbs that use the preposition por to indicate the cause or reason
The preposition por often appears after communication verbs when expressing the cause, motive, or channel.
pedir por alguien or enviar por alguien is less common for communication, but you will see pedir perdón por algo where por marks the reason: pedir perdón por equivocarse.
agradecer por is sometimes used colloquially, but the standard construction is agradecer a alguien por algo in many dialects: agradecer a María por su ayuda. Note that some grammarians prefer agradecer a alguien algo without por.
Examples
Pidió perdón por llegar tarde.
Le agradecí a Ana por su consejo.
Special verbs and prepositional patterns
Certain verbs require specific prepositions that are not always predictable. Learn common pairs and memorize examples because patterns vary between verbs.
insistir en: insist on. Use en to introduce the topic or action insisted upon: insistir en la importancia.
conversar con: converse with. Use con to indicate the person with whom you converse.
encontrarse con and hablar con: many verbs use con when the focus is on someone with whom you interact directly.
Examples
Insistió en que fuéramos temprano.
Conversé con mi profesor después de clase.
Hablé con ella por teléfono.
The pronoun le and the personal a: important notes
Spanish uses the personal a before direct objects that are specific people or pets. After many communication verbs, you may see both the preposition a and the indirect object pronoun le or les. This is typical and grammatically correct.
Example: A María le dije la verdad. Here the phrase starts with A María to clarify the person and uses the pronoun le as redundant indirect object. This double marking is common in Spanish for emphasis or clarity.
When using pronouns alone, you often omit the prepositional phrase: Le dije la verdad. Using both is optional but common when naming the person explicitly: A María le dije la verdad.
Using infinitives and subordinate clauses after communication verbs
After many communication verbs, the structure changes depending on whether you use an infinitive, que + clause, or direct object.
Verbs like decir, contar, explicar often introduce a subordinate clause with que: dijo que vendría, explicó que era difícil.
After verbs like preguntar, you can use si or que to introduce indirect questions: preguntó si vendrías; preguntó qué hora era.
Infinitives are used when the verb introduces an action rather than a clause: Me dijo venir mañana is colloquial; more standard is Me dijo que viniera mañana or Me pidió que viniera mañana. Use infinitives mainly after verbs like pedir + infinitive: Me pidió ayudarle.
Examples
Dijo que no podía asistir.
Le pregunté si quería café.
Ella pidió cerrar la puerta.
Regional and register differences
Preposition use can vary by region and formality. For example, some speakers say agradecer por while others prefer agradecer a alguien por or agradecer a alguien algo. In Latin America you will often hear usar or preferir certain constructions that differ slightly from Peninsular Spanish.
Informal spoken Spanish sometimes omits prepositions or uses shorter constructions. In formal writing, prefer explicit prepositions and standard constructions: preguntar a alguien, hablar de algo, insistir en algo.
Common mistakes and how to avoid them
Confusing a and de: Remember a often marks the person and de marks the topic. Wrong: pregunté a la película. Correct: pregunté sobre la película or pregunté por la película.
Forgetting the personal a: When the direct object is a specific person, include a. Wrong: Vi María en la fiesta. In many contexts you need Vi a María en la fiesta.
Using the wrong preposition with hablar: Do not use hablar a to mean speak about. Use hablar con or hablar de depending on meaning: hablar con alguien means speak with someone; hablar de algo means talk about a topic.
Examples of mistakes vs correct forms
Mistake: Hablé a mi amigo sobre el proyecto.
Correct: Hablé con mi amigo sobre el proyecto.
Mistake: Pregunté María la hora.
Correct: Le pregunté a María la hora.
Practical tips to learn prepositions after communication verbs
Group verbs by preposition: create lists for verbs that take a, de, con, por, and en. Memorize common collocations like preguntar a, hablar de, conversar con, insistir en.
Learn fixed expressions: Some verbs combine with fixed prepositional phrases, for example pensar en, so be attentive to those patterns.
Pay attention to redundancy with pronouns: It is natural in Spanish to use the indirect object pronoun plus the prepositional phrase for clarity. Practice both forms: Le dije and A Juan le dije.
Listen to native speech and read examples: Context helps solidify which preposition sounds right with each verb. Note variations by country and register.
Cultural and usage notes
Politeness and indirectness: Spanish often prefers indirect phrasing for requests and questions. Using verbs like preguntar, pedir, and decir with subordinate clauses or conditional forms can sound more polite: Quisiera preguntar si es posible…, rather than a blunt direct question.
Formality: In formal or written Spanish you may see more explicit prepositional structures and avoid colloquial shortcuts. In casual speech, prepositions might be shortened or dropped in fast conversation, but learning the full forms is best for clarity.
Summary of common verb + preposition pairs
Here are frequent combinations to remember: decir a alguien, preguntar a alguien / preguntar por / preguntar sobre, hablar con alguien / hablar de algo, contar a alguien / contar algo, explicar a alguien, insistir en algo, conversar con alguien, informar de / informar sobre.
Practice recognizing whether the element after the verb is a person (use a or con) or a topic/reason (use de, sobre, por, or en depending on the verb).
Conclusion
Understanding prepositions after communication verbs takes time, but learning common patterns and studying examples will make Spanish much clearer. Focus on whether the following word is a person or a topic, memorize typical verb-preposition pairs like preguntar a, hablar de, and conversar con, and practice listening to natural speech. Over time these structures will feel natural and will improve both your comprehension and expression.
