What Does It Mean to "Understand"?

*last updated on January 22, 2026

Have you ever thought about the word “understand” as being surprisingly hard to understand?

Have you ever had a moment when language feels unhelpful—when a familiar word suddenly turns slippery in your hands? I get this feeling a lot. When it happens, I do something very basic: I open a dictionary. This doesn’t “solve” the problem (a dictionary can’t rescue us from every ambiguity), but it often reveals why the problem exists in the first place.

Consider the definitions in Merriam-Webster. To “understand” can mean, among other things:

to grasp the meaning of something
to grasp the reasonableness of something
to have thorough or technical acquaintance with something
to be thoroughly familiar with the character or tendencies of something
to accept something as true or plausible without absolute certainty
to interpret something in one of several possible ways
to supply in thought what is left unsaid
to have the power of comprehension
to grasp the nature, significance, or explanation of something
to infer or believe something to be the case
to show a sympathetic or tolerant attitude
to feel sympathy for someone’s feelings or situation

These definitions clearly belong to the same family; we are not dealing with homonyms. And yet the breadth of meanings here is large enough that “understand” can generate misunderstanding all by itself. That is, the trouble isn’t that the word is “wrong.” The trouble is that we often use it as if it were a single, precise tool—when it is really a whole toolkit.

Take a common claim: “I understood the book.” What might this mean? It could mean:

Linguistic understanding (decoding):
I know what the words and sentences say. I speak the language, recognize the idioms, and can follow the surface meaning.
Conceptual or technical understanding (competence):
I grasp the concepts well enough to explain them or use them. If the book is technical, I can apply its terminology appropriately; if it’s philosophical, I can restate its main distinctions without distorting them.
Logical understanding (reasonableness):
I see how the argument hangs together. Even if I disagree, I can trace the steps from premises to conclusion and identify what would have to be true for the argument to work.
Interpretive understanding (meaning-as-reading):
I developed an interpretation of what the book is doing. But here the word “understand” crosses a threshold: it starts to imply that there is a single meaning to grasp, rather than many meanings to negotiate.
Contextual understanding (placement):
I can situate this text in a wider landscape. I know something about its genre, historical moment, intellectual influences, audience, and the conversations it is responding to.

And these aren’t mutually exclusive. We often mean several at once—without noticing that we are stacking different claims under one word.

This doesn’t apply only to books. It applies to any “text” in the broad sense: films, news articles, photographs, social media posts, museum exhibits, websites, even a brief headline. It also applies to the challenge of interpreting visual art. For example, how do we make sense of the art piece in the picture above? Are we trying to identify what it is (a creature, an abstract form, a joke, a symbol), or what it does (unsettles, invites empathy, signals status, provokes disgust), or what it means—and for whom?

Sometimes “understanding” is less like opening a lock and more like entering a room with multiple doors, where the best you can do is explore carefully and stay honest about what you’re assuming.

When we don’t attend to these nuances, it becomes easy to slip into two habits:

Treating our interpretation as the interpretation.
We say “I understand it” and quietly mean “I have the correct reading.”
Assuming that correct understanding should be possible.
We expect that if we try hard enough, we should be able to know what the text really means.

But many theories of interpretation challenge that expectation. Roland Barthes’s “The Death of the Author," for example, is often read as a critique of the idea that the author’s intentions can anchor a text’s final meaning. Even if a writer sincerely explains what she “meant,” that explanation does not necessarily settle what the text does in the world—or how it will be read by different people, in different contexts, with different histories.

There is also a more intimate complication: even if we set aside the problem of readers, how sure are we that any person fully understands her own creations? A writer may be aware of her goals and experiences, but no one can map every influence, assumption, half-remembered story, or cultural pattern that shaped her thinking. The more you reflect on the possibility of understanding a text, the more it begins to touch a broader philosophical question: What does it mean to understand ourselves?

Then there is the other use of the word—the one that matters in daily life, and especially in conflict. What do we mean when we say “I understand you” or “I don’t understand them”?

Again, “understand” may refer to several different things:

Comprehension: I can follow what you’re saying.
Prediction: I can anticipate how you’re likely to react.
Explanation: I can trace how your view makes sense from your premises or experiences.
Recognition: I can name what you might be feeling, even if I don’t share it.
Empathy or compassion: I can relate emotionally, or I can respond with care.
Moral agreement: I think your reasons are good reasons; I endorse them.

In polarized times, these get blended together in ways that intensify division. I often hear people say: “I’ll never understand how somebody can do this!” That phrase fascinates me because it can mean at least three different things:

I can’t imagine myself doing it (a statement about personal identity).
I can’t see how it could make sense (a statement about intelligibility).
I refuse to grant it legitimacy (a statement about moral judgment).

Those are not the same. But when we compress them into “I’ll never understand,” we may accidentally imply that explanation equals endorsement—or that any attempt to explain is already a step toward excusing.

Here is a distinction I want to hold firmly:

Understanding the logic behind an action is not the same as saying the action is acceptable.
Explaining is not excusing.

In my view, we can (at least in principle) grasp the internal logic behind any action—even actions we find morally wrong. This doesn’t mean we soften our judgment, abandon our values, or stop resisting harm. It means we refuse the intellectual shortcut of calling a person “irrational” simply because their reasoning is not our reasoning.

Why does this matter? Because shallow explanations tend to create shallow responses. If we tell ourselves that harmful actions come from people who are simply “mean” or “stupid,” we may get the momentary comfort of certainty—but we also lose information. We stop asking what conditions, fears, incentives, loyalties, narratives, and social rewards are shaping the behavior. We stop asking what kinds of meaning-making are at work.

And sometimes we avoid looking precisely because the word “understand” feels morally dangerous. Many people seem to sense (not unreasonably) that once you understand the origin of a radically different worldview, you might start to accept it. But that is exactly where the ambiguity of “understand” can trap us. If “understand” is heard as “sympathize,” “agree,” or “forgive,” then curiosity becomes suspect. I don’t think it should.

Condemning specific actions—and doing our best to stop the person behind them from causing harm—should not prevent us from looking for deeper reasons for those actions. In fact, the willingness to understand in the explanatory sense may be one of the most practical tools we have for interrupting harm, reducing conflict, and resisting the flattening effects of polarization. Not because understanding automatically makes people good. But because refusing to understand often makes us blind.
