What is the difference between casar and casarse?
The verb casar is generally transitive: it means to marry someone or to perform a marriage (often used for officiants or arrangements). The reflexive form casarse means to get married or to marry (emphasizing that the subject participates in the marriage). In short, casar often requires a direct object, while casarse focuses on the subject becoming married.
Simple rule
Use casar when someone marries another person (performing the action). Use casarse when someone gets married (experiences the change of marital status).
Casar: to marry someone (transitive)
When you want to say that a person or an official marries another person, use casar plus a direct object: casar a alguien. This structure tells who performs the marriage or who causes the marriage to happen.
Examples with casar
El juez casó a los novios en la plaza.
La madre quería casar a su hija con un buen partido.
El cura casó a la pareja el sábado pasado.
Notice in these sentences the focus is on the person who performs the action. In El juez casó a los novios, the judge performed the marriage ceremony. In La madre quería casar a su hija, casar carries a somewhat archaic or formal tone when used for arranging marriages.
Casar used in passive or se constructions
You may also see passive or impersonal constructions with casar. For example: Se casó a los novios en la iglesia. This uses the reflexive se to form an impersonal passive meaning the ceremony was performed; however this construction is less common than using casar with an explicit agent.
Casarse: to get married (pronominal/reflexive)
The reflexive verb casarse describes the state or action of getting married. It is used when the subject experiences the marriage. With casarse the person doing the action and the person receiving the action are the same, so reflexive pronouns are required: me, te, se, nos, os, se.
How to form basic sentences with casarse
Subject + reflexive pronoun + conjugated casarse. Examples: Me casé, Te casas, Se casaron, Nos casaremos. Add con + person to indicate with whom: Se casó con Juan.
Examples with casarse
Voy a casarme el próximo verano.
María se casó con Pedro en septiembre.
Mis padres se casaron muy jóvenes.
Here the subject is the one getting married. The phrase se casó con Pedro clearly means Maria got married to Pedro.
Conjugation highlights and useful tenses
Below are common conjugations you will see often. Use the corresponding reflexive pronouns when using casarse. For casar the verb is conjugated normally and takes a direct object.
Present
Yo me caso / Tú te casas / Él/Ella se casa / Nosotros nos casamos / Vosotros os casáis / Ellos se casan
Preterite (completed past)
Yo me casé / Tú te casaste / Él/Ella se casó / Nosotros nos casamos / Vosotros os casasteis / Ellos se casaron
Future
Yo me casaré / Tú te casarás / Él/Ella se casará / Nosotros nos casaremos / Vosotros os casaréis / Ellos se casarán
Conditional
Yo me casaría / Tú te casarías / Él/Ella se casaría / Nosotros nos casaríamos / Vosotros os casaríais / Ellos se casarían
Common sentence patterns and prepositions
Understanding prepositions helps form natural sentences. With casarse, use con to indicate the partner. With casar, you can use a direct object or con depending on focus.
Casarse + con
When indicating the person someone marries use: se casó con + name. Example: Se casó con Ana. If you want to add location or time, use en or a: Se casaron en la playa en junio.
Casar a alguien
When indicating who was married by someone use: casar a + person. Example: El alcalde casó a la pareja. You can also say casar a alguien con alguien else to indicate arranged marriages: Los abuelos casaron a su hija con un buen hombre.
Negative, questions, and reflexive pronoun placement
Placement of reflexive pronouns follows normal Spanish rules. In affirmative conjugated verbs, place the pronoun before the verb. With infinitives, attach to the end or place before the auxiliary.
Examples
No me voy a casar todavía.
No voy a casarme todavía.
¿Te casaste el año pasado?
¿Se van a casar este verano?
Both No me voy a casar and No voy a casarme are correct. In the infinitive construction, attaching the pronoun to the infinitive is common and natural.
Differences in nuance and register
Using casar to mean arrange or marry someone can sound formal or old-fashioned in some contexts. For everyday conversation, learners will most often use casarse to say get married. Use casar when emphasizing the person who performs the wedding or when talking about arranged marriages or legal officiation.
Examples contrasting nuance
La pareja se casó en el ayuntamiento. (They got married at city hall.)
El juez casó a la pareja en el ayuntamiento. (The judge married the couple at city hall.)
Both sentences describe the same event, but the first emphasizes the couple’s action, the second emphasizes the judge’s role.
Compound verbs and related vocabulary
Several verbs relate closely to casar and casarse. Knowing them helps you describe ceremonies and legalities.
Casamiento: wedding, marriage ceremony.
Nupcias: nuptials, formal term for wedding.
Contraer matrimonio: a formal expression meaning to enter into marriage, similar to casarse. Example: Contrajeron matrimonio en una ceremonia íntima.
Using contraer matrimonio
Contraer matrimonio is more formal and common in legal documents. In everyday speech, most people say casarse or casarse con alguien.
Cultural and usage notes
In many Spanish-speaking countries, civil and religious ceremonies are distinct. People often say se casó civilmente for the legal marriage and tuvo una boda religiosa for the church ceremony. Also, families sometimes use casar in contexts of arranged relationships or matchmaking, which can carry cultural connotations especially in older generations.
When discussing same-sex marriages or modern partnerships, use the same verbs: se casó con su pareja, nos casamos, or contrajimos matrimonio. Language adapts; the grammar remains the same regardless of the partners involved.
Common mistakes and how to avoid them
1. Forgetting the reflexive pronoun with casarse: Saying casó instead of se casó changes the meaning.
2. Using casar when you mean casarse: El novio casó is incorrect if you mean the groom got married; you need El novio se casó.
3. Overusing casar for everyday speech: Native speakers usually say casarse when referring to people getting married.
Remember: if the subject is the one who becomes married, use casarse with the correct reflexive pronoun. If someone performs the marriage or arranges it, use casar with a direct object.
Additional real-life examples
Mis abuelos se casaron en 1950 y celebraron bodas de oro en 2000.
La agencia quería casar a los jóvenes con parejas compatibles.

These examples show everyday and more formal uses, and how to combine time and place details to make natural sentences.
Conclusion
Understanding the difference between casar and casarse is simple once you remember the transitive versus reflexive distinction. Use casar when someone marries or officiates, and use casarse when someone gets married. Practice with real sentences, pay attention to reflexive pronouns, and listen for natural usage in conversations and media to master these verbs.
