The word lo in Spanish is commonly used in daily conversations –lo siento, no lo vi, lo que dices. Sounds familiar? However, this word can be confusing since it has multiple meanings and applications. So, in this guide, you’ll learn how and when to use lo in Spanish. 

Here is an overview of what we’ll cover: 

To make things easier, I’ve included common sentences with lo that can help you understand this word. 

What Is Lo in Spanish

In Spanish, lo is an invariable word. Simply put, it has a single form and has no gender or plural form. Depending on the elements of the sentence, lo can be a pronoun or a neuter article: 

No lo puedo hacer. 
I can’t do it

Lo que quiero es que me ayudes. 
What I want is for you to help me. 

Lo bueno es que no pasó nada. 
The good thing is that nothing happened. 

Notice that since it cannot provide information about the number or gender of a noun, lo is never followed by nouns. 

The elements it works with define the type of word lo is in a sentence. In the sections below, we’ll learn the different structures we must use to apply this term correctly. 

Take Note: There are no neuter nouns in Spanish. In fact, one of the main characteristics of Spanish nouns is that they have gender and number. As a result, the adjectives or determiners you use (such as articles) must also convey this information. 

How & When to Use Lo in Spanish

The graphic below shows the most common uses of lo in Spanish:

As you can see, the meaning and translation of lo will vary depending on the application. Let’s dive into each use so you get familiar with them. 

1. Direct object pronoun lo

Lo works as a Spanish direct object pronoun when replacing a masculine singular noun. This noun receives the action of the verb. In this case, lo is the equivalent of ‘him’ or ‘it’. 

Ella lo rompió. 
She broke it

Lo perdoné porque lo amo. 
I forgive him because I love him

¿Ya conoces a Juan? Yo lo conocí ayer. 
Have you met Juan? I met him yesterday. 

El pastel está destruido. No puedo arreglarlo
The cake is destroyed. I can’t fix it

Take Note: Direct objects can be people, animals, or things. But, to replace them, people must know or understand what you’re talking about. 

2. Neuter article lo

The neuter article lo is used with adjectives or adverbs to emphasize and talk about a quality or abstract idea. This Spanish neuter article can be translated as ‘the’ or ‘as’. Here are some examples: 

Lo + [adjective / adverb]

Eso no es lo peor
That’s not the worst.

Ven lo más rápido que puedas. 
Come here as fast as you can. 

Lo importante es que estés bien. 
The important thing is that you’re okay.

Eres lo mejor que me ha pasado. 
You’re the best thing that ever happened to me. 

Check example #2. The neuter article lo can be used to form comparatives in Spanish. Also, you can combine this word with possessives and other types of adjectives:

Lo mío es aprender idiomas. 
My thing is learning languages. 

No se le quita lo arrugado.
The wrinkles don’t go away.

Take Note: In Spanish grammar, lo + adjective is the formula to transform an adjective into a noun. We do this to emphasize qualities or talk about abstract ideas. Since we’re emphasizing, lo may not always have a direct translation into English.

3. Relative expressions: lo que

Lo que refers to implicit statements, concepts, or ideas previously discussed. So, in this application, the pronoun lo means ‘what’ or ‘which’. A conjugated verb must follow this structure: 

Lo que + [conjugated verb]

Eso no fue lo que dije
That’s not what I said

Lo que Jack quiere decir es que…
What Jack means to say is that…

Tranquila, no es lo que parece
Easy, it’s not what it looks like

Lo que significa que estamos en problemas. 
Which means that we’re in trouble. 

Take Note: Relative pronouns in Spanish allow you to combine two sentences together and avoid repetition. In short, they’re crucial for clear communication. 

4. Replaced concepts previously mentioned

As a pronoun, lo allows you to replace implicit topics or ideas (that were previously mentioned). For instance, we often use this word to respond to questions with the verb ser

Lo + [conjugated verb]

No lo sé. 
I don’t know. 

Lo sentimos mucho. 
We’re very sorry. 

Persona 1: Hija, ¿eres feliz?Person 1: Are you happy, daughter?
Persona 2: Sí, papá lo soy. Person 2: Yes, dad, I am. 

The pronoun lo may not have a direct English translation in this application. 

You can also use the structure lo + de + noun to talk about an implicit situation or event:

¿Supiste lo de Laura?
Did you hear about Laura?

¿Qué pasó con lo del proyecto?
What’s going on with the project?

Spanish Grammar: Lo vs Le in Spanish

When it comes to Spanish pronouns, lo and le are often confused because they both replace singular masculine nouns. However, these pronouns are far from being interchangeable. 

The direct object pronoun lo replaces a noun that receives the action of the verb. On the other hand, le replaces an indirect object or the person or thing to or for whom we do something: 

Ella no lo quebró. 
She didn’t break it

Nosotros le compramos un celular. 
We bought him a phone.
