Basic Spanish rules for using “Con” and “Sin” in notes

Introduction

Learning how to use basic prepositions can make your Spanish notes and signs clear and professional. This guide explains when and how to use con and sin in everyday notes, menus, reminders, and forms. You will get vocabulary, practical examples, common mistakes, and easy tips targeted to complete beginners.

What are con and sin?

con means with. Use it to indicate accompaniment, inclusion, or presence of something or someone.

sin means without. Use it to indicate absence, exclusion, or lack of something.

Basic grammar rules

Both con and sin are prepositions that sit before nouns, pronouns, or infinitives. They do not change form for gender or number. Place them directly before the word they modify. Example order is usually preposition + noun.

When a verb follows, you often use the preposition + infinitive. For example:

Ve con cuidado

is literally go with care, so use con before the noun that indicates manner. For absence of action:

No salgas sin avisar

uses sin + infinitive.

Using con and sin in short notes and labels

Beginners often write short notes, grocery lists, or labels. Keep them simple: preposition + noun.

Examples for kitchen notes:

Leche con cacao

Café sin azúcar

Pan con mantequilla

Ensalada sin cebolla

Practice: signs and labels

When labeling food or containers, use con to highlight ingredients and sin to warn about missing ingredients or allergens.

Examples for containers:

Yogur con frutas

Sopa sin gluten

Jugos con hielo

Arroz sin sal

Notes for people: presence or absence

Use con to show someone is included or will attend, and sin to show someone is absent or unavailable.

Examples for appointment notes:

Cita con Carolina a las 10:00

Reunión sin Luis

Trabajo con equipo nuevo

Día libre sin guardias

Common phrases beginners will use

Here are practical short phrases you might write in messages or sticky notes.

Ven con tu identificación — come with your ID

No entres sin permiso — do not enter without permission

Reserva con tarjeta — reserve with card

Comida sin picante — food without spice

Using con and sin with verbs

Place con or sin before an infinitive to show how an action is done or not done. This structure is common in warnings, instructions, and reminders.

Examples:

Entrar con cuidado — enter carefully

Salir sin zapatos — leave without shoes

Trabajar con atención — work with attention

No hablar sin levantar la mano — do not speak without raising your hand

Common mistakes and how to avoid them

1. Using con/sin with verbs incorrectly. Remember to use the infinitive after the preposition when the verb is the action detail. Wrong:

No entrar sin que llamar

Correct:

No entrar sin llamar

2. Confusing agreement. Con and sin do not agree in gender or number, so do not change them. Wrong:

Cons

or

sins

— these do not exist. Correct:

con amigos

and

sin amigos

3. Omitting no for negative commands. If you mean do not do something, include no before the verb plus sin when needed. Example:

No salgas sin abrigo

— do not leave without a coat.

Practical tips for writing clear notes

Keep notes short and place the preposition directly before the item it modifies. For allergies or important details, use sin at the start to emphasize absence. For added ingredients or necessary items, put con near the ingredient.

Tip examples:

Allergen note: Sin cacahuates

Include item: Con cargador

Reminder: No entrar sin máscara

How to expand vocabulary around con and sin

Learn common nouns that follow these prepositions in everyday contexts: comida, bebida, cita, permiso, tarjeta, identificación, entrada, salida. Practice creating short notes using those nouns with con and sin.

Example practice set:

Write 5 grocery labels using con and 5 using sin. Example answers:

Beginner-friendly reminders for pronunciation and writing

You do not need special pronunciation rules for these prepositions; they are short and clear. Focus on spelling: c-o-n and s-i-n. In handwriting, keep them separate from the following word with a space.

When typing notes, use lowercase for short labels unless it is a title or the start of a sentence. Example:

leche con cacao

looks natural on a label.
