If you’ve spent more than five minutes trying to learn Spanish, you’ve definitely run into it. It’s everywhere. You’re listening to a podcast or trying to order a coffee, and suddenly the speaker drops a "lo que" into the middle of a sentence. It doesn’t mean "it that." It doesn’t mean "the what." Honestly, it’s one of those linguistic hurdles that makes English speakers want to throw their textbook across the room because it feels like a glitch in the matrix.
But it’s not a glitch. Lo que is actually the secret sauce of natural Spanish.
Understanding what does lo que mean isn't just about memorizing a dictionary definition. It’s about understanding how Spanish handles abstract ideas. In English, we have the luxury of using the word "what" in two different ways. We use it to ask a question (What are you doing?) and we use it to describe a thing (I like what you’re doing). Spanish is way more pickier. It uses qué for the question and lo que for the thing. Without this little phrase, you’re stuck speaking in "Caveman Spanish," unable to connect complex thoughts or describe things you don't have a specific noun for.
The "What" That Isn't a Question
Let’s get the biggest misconception out of the way immediately. Most beginners see "que" and think "that" or "what." They see "lo" and think "it." So, they assume lo que means "it that."
Stop. Don't do that.
Think of lo que as a single unit. It functions as a relative pronoun. Specifically, it’s a "neuter" relative pronoun. Because Spanish is a gendered language, everything is usually a "he" or a "she." But what happens when you’re talking about an idea? An action? A situation? You can't give a "situation" a gender easily if you haven't named it yet. That’s where the "lo" comes in. It acts as a placeholder for a concept that hasn't been defined.
Consider this: "I don't know what he wants." In Spanish, if you say "No sé qué quiere," you’re emphasizing the mystery of the specific object. But if you say "No sé lo que quiere," you’re referring to the entire concept of his desires. It’s a subtle shift, but it’s the difference between sounding like a tourist and sounding like a local.
Why You Can't Just Say "Qué"
English is lazy. We use "what" for everything. Spanish prefers precision.

If you use qué (with the accent mark), you are asking for information. It’s an interrogative. Even in indirect questions like "He asked what I was eating," you’re still dealing with a question-adjacent structure. However, lo que is used when "what" could be replaced by "the thing that" or "that which."
Try this trick: Read your English sentence. If you can swap "what" for "the thing that" and it still makes sense, you need to use lo que.
- "What (The thing that) he said was a lie." -> Lo que dijo era mentira.
- "I like what (the thing that) you're wearing." -> Me gusta lo que llevas puesto.
It’s basically a bridge. It connects a verb to an idea without needing a middle-man noun. You don't need to say "I like the shirt that you are wearing" (Me gusta la camisa que llevas). You can just jump straight to the point. This is why you'll hear it constantly in street slang and academic lectures alike. It's efficient.
Breaking Down the Grammar Without Falling Asleep
I know, grammar talk is usually a snooze-fest. But look, if you want to master what does lo que mean, you have to look at the "lo." In Spanish, "lo" is the king of the abstract.
When you attach "lo" to an adjective, you turn that adjective into a noun. Lo bueno (the good thing), lo malo (the bad thing), lo importante (the important part). Lo que follows this same logic. It takes the relative pronoun "que" and anchors it to a non-specific "thing."
There are actually three main ways you're going to see this used in the wild:
At the start of a sentence to introduce a topic.
"Lo que necesito es un café." (What I need is a coffee.) Here, it’s setting the stage. You’re highlighting the object before you even say what it is.👉 See also: 100 Biggest Cities in the US: Why the Map You Know is Wrong
In the middle of a sentence to refer back to an entire idea.
"Él llegó tarde, lo que me molestó mucho." (He arrived late, which annoyed me a lot.) Notice that "lo que" isn't referring to "him" or "the time." It’s referring to the entire fact that he was late.To describe an unknown or unnamed object.
If you're pointing at a weird tool in a hardware store and don't know the name, you’d say, "Dame lo que está en la mesa." (Give me the thing that is on the table.)
Common Mistakes That Make Natives Cringe
The most frequent error? Using eso que or just que when you should be using lo que.
If you say "Me gusta que dijiste," a Spanish speaker will wait for you to finish the sentence because it sounds like you’re saying "I like that you said..." and then trailed off. It’s incomplete. You need that "lo" to act as the "thing."
Another pitfall is the confusion with cual. While lo cual exists and is often interchangeable with lo que, it’s much more formal. You’ll find lo cual in legal documents or high-brow literature. If you’re at a bar in Madrid or a taco stand in Mexico City, stick to lo que. It’s warmer. It’s more natural.
Also, watch out for the accent. Qué (with the accent) is for questions. Que (without the accent) is "that." Lo que never takes an accent on the "que." If you put one there, you're essentially writing "the what?" which makes zero sense to a reader.
Seeing It in Action: Real World Examples
Let's look at how this actually sounds in conversation. Spanish is a language of emotion and emphasis.

Imagine you're arguing with a friend. You might say:
"¡Eso es lo que yo digo!" (That is what I'm saying!)
In this case, lo que is doing the heavy lifting of emphasizing your point. It’s not just "that's my word," it's "that is the entirety of my argument."
Or think about a romantic setting.
"Eres lo que siempre soñé." (You are what I always dreamed of.)
Again, "lo que" encompasses everything about the person—their personality, their look, their vibe. It’s much more encompassing than saying "You are the person I dreamed of." It’s poetic because it’s vague yet all-consuming.
Practical Steps to Master Lo Que
Don't try to learn this by staring at a conjugation chart. It won't help. This is a functional phrase, not a grammatical chore.
Start by "shadowing." When you watch a show in Spanish—maybe something like La Casa de Papel or even just YouTube vlogs—listen specifically for the "lo." You’ll start to notice it pops up right before a verb almost every time.
Next, try to replace "the thing that" in your daily English thoughts with the Spanish phrase. If you’re thinking, "I forgot the thing that I had to do," say to yourself, "I forgot lo que I had to do." It sounds silly, but it builds the mental pathway.
Finally, stop worrying about the literal translation. Translation is a trap. Language is about mapping ideas to sounds. In Spanish, the idea of "an unspecified thing or concept" is mapped to the sound lo que.
Next Steps for Your Spanish Journey:
- Audit your speech: The next time you speak Spanish, count how many times you used qué when you actually meant "the thing that."
- Practice "Lo + Adjective": Before mastering the full phrase, get comfortable with the neuter "lo" by using phrases like lo mejor (the best thing) or lo interesante (the interesting part).
- Rewrite three sentences: Take three basic sentences like "I know what you want," "What he has is cool," and "I don't like what is happening," and translate them using the "the thing that" rule.
- Listen for the "Which" connection: Pay attention to how often you use "which" in English to refer back to a whole sentence. Practice replacing that connection with lo que in your Spanish practice.
