Introduction
Learning Spanish capitalization is one of the easiest ways to look more confident in reading and writing. This guide explains simple, practical rules for beginners using Latin American standard Spanish. Short examples, common mistakes, and useful vocabulary make it simple to start applying these rules right away.
Why capitalization matters in Spanish
Capitalization helps readers identify names, sentence starts, titles, and formal terms. In Spanish, some rules differ from English. Knowing the key differences prevents common beginner errors and improves clarity in messages, forms, menus, and signs.
Basic rule: start sentences with a capital
Every sentence starts with a capital letter. This is the most basic rule and matches English. It applies to full sentences and independent clauses that begin a sentence.
Example:
Hola, ¿cómo estás?
Gracias por tu ayuda.
Proper nouns and names
Capitalize names of people and specific places. Use capitals for first names, last names, and official names of cities and countries.
Example:
María trabaja en Bogotá.
El señor Pérez llegó tarde.
Titles, ranks, and professional forms
Capitalize official titles only when used with names. In Spanish, titles like presidente, doctor, or profesor are usually lowercase unless they directly precede a name as a formal address in some contexts.
Examples:
El presidente López habló hoy.
La doctora García es muy amable.
Mi profesor de español es amable.
Days, months, and languages
Do not capitalize days, months, or names of languages. Unlike English, Spanish uses lowercase for these common words.
Example:
Mi cumpleaños es en marzo.
Nos vemos el lunes.
Estudio español e inglés.
Nationalities and adjectives
Adjectives of nationality are lowercase. Words describing origin or nationality are not capitalized in Spanish.
Example:
Ella es mexicana.
Compré café colombiano.
Capitalization in titles and headings
Use sentence-style capitalization for titles. In Spanish headings and titles, only the first word and proper nouns are capitalized.
Examples:
La casa en la colina
Cómo aprender español fácilmente
Common special cases
Months and seasons
Months and seasons stay lowercase. This often surprises English speakers, so remember to keep marzo, abril, verano, otoño lowercase.
Example:
El verano pasado fui a la playa.
Days of the week
Days are lowercase. Use lunes, martes, miércoles, jueves, viernes, sábado, domingo.
Example:
Tengo clase el miércoles y el viernes.
Religions and religious terms
Religious terms are lowercase unless part of a proper name. Words like católico or cristiano are lowercase, but a specific church name is capitalized.
Examples:
Es católica.
Iglesia de San Pedro
Company names and brands
Company and brand names follow the brand’s own capitalization. When a company uses a capital letter as part of its name, keep it. Otherwise, treat it like a proper noun.
Example:
Trabajo en Banco Nacional.
Compré un teléfono de la marca Claro.
Abbreviations and acronyms
Abbreviations usually use capitals. Common abbreviations like Sra., Sr., Dr., and acronyms like ONU, OEA are capitalized. When writing abbreviated names of titles, include a period when customary.
Examples:
La Sra. López llegó temprano.
La ONU publicó un informe.
Practical beginner tips and examples
Filling forms and writing emails
When entering names on a form, capitalize the first letter of each name: Nombre: Juan Apellido: García. For addresses, capitalize street names that are proper nouns: Calle San Martín.
Email opening lines: Hola Ana, or Estimado señor Martínez, start with a capitalized greeting and the name.
Menus and signs
On restaurant menus, Spanish often uses sentence-style capitalization. The first word of each dish or item is capitalized; ingredients remain lowercase unless proper nouns.
Examples:
Ensalada César
Arroz con pollo
Social media and messages
Casual messages may skip capitals, but for learning and formal communication, start sentences with capitals and capitalize names. This looks more polite and clear.
Example:
¿Vas al cine mañana, Carlos?
Public signs and notices
Public signs usually capitalize the first word and proper nouns. Learn common phrases so you recognize what to capitalize on signs.
Examples:
Salida de emergencia
Prohibido fumar
Common beginner mistakes and how to avoid them
Over-capitalizing days and months
Mistake: Writing Agosto instead of agosto. Remember months are lowercase.
Fix: Learn a short rule: months and days are lowercase in Spanish.
Capitalizing adjectives of nationality
Mistake: Writing Mexicano instead of mexicano. Nationalities are adjectives and stay lowercase.
Fix: If the word describes origin or language, use lowercase.
Capitalizing all words in titles
Mistake: Learning English title-style and applying it to Spanish, for example: El Libro De La Vida. Spanish uses sentence capitalization.
Fix: Capitalize only the first word and proper nouns: El libro de la vida.
Incorrect capitalization of professions
Mistake: Writing Profesor as a capital when not used as part of a name. Use lowercase unless part of a formal name in specific contexts.
Fix: Use lowercase for general professions: mi profesor, la ingeniera.
Quick reference summary
Always capitalize: first word of a sentence, names of people, official place names, company names as written.
Do not capitalize: days of the week, months, languages, nationalities, adjectives of religion, most titles when not used with names.
Capitalize in special cases: acronyms and formal abbreviations, proper nouns within titles.

Nombre: José (capitalize)
Apellido: Rodríguez (capitalize)
