Best Way to Memorize Abstract Concepts? Make Them Concrete
Why abstract ideas are only hard to remember while they stay abstract.
The best way to memorize abstract concepts is to stop letting them stay abstract: make them concrete and connect them to what you know. Abstract ideas are hard to remember precisely because they lack a sensory hook, the well-established concreteness effect, so the techniques that work all convert the abstract into something concrete: your own concrete examples, analogies to familiar things, turning the idea into an image or drawing, and elaborating by explaining why and how it connects to existing knowledge. The deepest move is to understand a concept and wire it into your web of knowledge rather than memorizing an isolated definition, because a connected idea has many routes back to it.
The best way to memorize abstract concepts is to stop treating them as abstract: make them concrete, turn them into images, and connect them to things you already know. Abstract ideas, a principle, a definition, a theory, are genuinely hard to remember, but not because your memory is weak. They are hard because they have no sensory hook, nothing to see, touch, or picture, and human memory is built to hold concrete things far better than abstract ones. So the whole game is conversion. Give the concept a concrete example, compare it to something familiar, draw it or picture it, and explain how it links to what you already understand. Do that and an idea that felt slippery and forgettable becomes something your memory can actually grip. And the deepest version of the technique is not memorizing the concept at all in the rote sense, but understanding it well enough that it connects to everything around it, which is what makes it stick.
Why are abstract concepts so hard to memorize?
Because your memory is built for the concrete, and abstract ideas give it nothing to hold. This is not a personal failing; it is how human memory works. Decades of research describe the concreteness effect: memory for concrete, easily imagined words is reliably better than for abstract ones. A word like apple or hammer comes with a built-in picture, a context, and a feel, and your brain stores it through both language and imagery. A word like justice or entropy activates only the verbal system, with no image to anchor it, so it is encoded thinly and forgotten easily. The same gap applies to whole concepts: a vivid, concrete idea sticks, while an abstract one slides away. Understanding this changes the strategy entirely. The problem is not that you need to try harder to memorize abstractions; it is that you need to make them less abstract, so your memory has something concrete to grab onto. Every good technique for abstract concepts is really a way of doing exactly that.
Make it concrete: examples and analogies
The fastest way to anchor an abstract idea is to attach it to a specific, familiar thing. This is the foundational move, and the research is clear on it. Because human memory remembers concrete information better than abstract, pairing an abstract idea with concrete examples and analogies makes it far easier to recall, and generating your own examples works best of all. A concrete example gives an abstract concept a body: do not just memorize that opportunity cost is the value of the next best alternative, attach it to the specific lunch you skipped to finish work. An analogy borrows a memory hook you already have, explaining the abstract thing in terms of something familiar, which is why electricity is taught as water in pipes. The crucial detail is to generate your own examples and analogies rather than borrow them, because the act of finding one forces you to actually understand the concept, and the personal, vivid instance you invent will stick far better than a generic one from a textbook.
| Technique | What you do | Why it works |
|---|---|---|
| Concrete examples | Give the idea a real, specific instance | Memory favors the concrete |
| Analogies | Compare it to something familiar | Borrows an existing memory hook |
| Dual coding | Turn it into an image or drawing | Stores it as words and a picture |
| Elaboration | Explain why and how, connect it | Wires it into what you know |
Turn it into an image: dual coding and visualization
Give the concept a picture, even an invented or absurd one, and you store it twice. The next technique attacks the concreteness problem directly by manufacturing the imagery abstract ideas lack. This is dual coding: representing the same idea in both words and a visual, so you have two routes to recall instead of one. The visual does real work, not decoration: turning information into a drawing improves memory and helps overcome the disadvantage abstract material normally carries, because producing a visual forces you to process and represent it. For abstract concepts this often means inventing a synthetic image, a deliberately vivid or strange little scene that stands in for the idea. To remember that inflation erodes purchasing power, picture your wallet literally shrinking as prices balloon. The image does not need to be accurate or elegant; it needs to be vivid and yours, which is the principle behind using intense, vivid mental imagery to make ideas unforgettable. Drawing it yourself, however badly, beats just picturing it, and when you need several related concepts in a fixed order, you can place those invented images along a familiar route and walk it in your mind, the method of loci that memory champions rely on.
Elaborate: connect it to what you already know
The most durable move is to wire the concept into the web of things you already understand. Concrete examples and images make a concept memorable; elaboration makes it understood, which is sturdier still. Elaboration means explaining the idea in your own words and asking how and why it works, then connecting it to related ideas, how it resembles one thing and differs from another. This matters because understanding is knowing how a concept connects to what you already know, and a concept that is connected to a dozen others has a dozen routes back to it in memory, while an isolated definition has only one fragile path. When you elaborate, you stop storing the concept as a standalone fact and start weaving it into your existing knowledge, so that recalling almost anything nearby can pull it back up. This is why the abstract concepts that stick are usually the ones you have argued about, taught, or applied: each of those acts forced you to connect the idea to everything around it.
The deepest move: understand it, don’t just memorize it
For abstract concepts, understanding is not a nice extra; it is the most reliable form of memory. There is a real difference between memorizing an abstract concept and understanding it, and for ideas rather than arbitrary facts, understanding wins decisively. A memorized definition is brittle: it sits alone, decays fast, and breaks the moment the wording changes. An understood concept is robust: because you grasp why it is true and how it connects to everything else, you could reconstruct the definition even if you forgot the exact words. This is why trying to brute-force memorize abstract concepts as definitions is the slowest, weakest approach available, while genuinely understanding them, through examples, images, and elaboration, makes them stick almost as a side effect. The goal with an abstract concept is not really to memorize it. It is to understand it so thoroughly, and connect it so widely, that forgetting it becomes difficult. Memory for ideas is mostly a byproduct of understanding, not a separate task.
What about rote memorization and spaced repetition?
Both still have a place, but for concepts they come second, after meaning. It would be wrong to suggest that memorization technique never matters. Some things genuinely are arbitrary, a specific term, a name, a number, and for those, classic tools like spaced repetition and even mnemonic images are exactly right. And even a well-understood concept benefits from spaced retrieval practice, recalling it from memory at increasing intervals, which strengthens the memory far more than rereading. The key is the order. For an abstract concept, you make it concrete and understand it first, and only then use spaced retrieval to lock that understanding in over time. Doing it the other way around, drilling a definition you do not understand, is the joyless, ineffective slog most people associate with memorizing abstractions. Understand first, then space the practice. The techniques are partners, but meaning leads and repetition follows, not the reverse.
How do you actually memorize an abstract concept?
Run it through a simple sequence: concretize, visualize, connect, then retrieve over time. The practical workflow ties the techniques together. Start by giving the concept your own concrete example, the more specific and personal the better. Then turn it into a vivid image, picturing or sketching a little scene that captures it, however strange. Next, elaborate by explaining it in your own words and connecting it to ideas you already hold, asking how and why it works and what it resembles. Finally, practice recalling it from memory at spaced intervals so the understanding sets. Notice that three of those four steps are really about building connections and understanding, not raw memorization, because for abstract ideas that is what memory actually rests on. You are not stuffing a definition into a slot; you are wiring a concept into a connected internal model, which is precisely what a first brain is and why it holds ideas better than any external store. The book Building Your First Brain covers how to build that connected understanding, and it is free for the first 1,000 readers.
Key takeaways: make it concrete, then connect it
The best way to memorize abstract concepts is to stop letting them stay abstract. Abstract ideas are hard to remember because of the concreteness effect, your memory holds concrete, imageable things far better than abstract ones, so the fix is conversion. Give a concept your own concrete example, compare it to something familiar with an analogy, turn it into a vivid image you picture or draw, and elaborate by explaining how and why it works and connecting it to what you already know. The deepest move is to understand the concept and wire it into your web of knowledge rather than memorizing an isolated definition, because a connected, understood idea has many routes back to it and is hard to forget. Make it concrete, give it an image, connect it, and then use spaced retrieval to set it. For ideas, durable memory is mostly a byproduct of understanding.
Frequently asked questions
What is the best way to memorize abstract concepts?
Make them concrete and connect them to what you know. Abstract ideas are hard to remember because they lack a sensory hook, so give each concept your own concrete example, compare it to something familiar with an analogy, turn it into a vivid mental image or drawing, and elaborate by explaining how and why it works and how it links to ideas you already hold. Then practice recalling it over spaced intervals. Conversion from abstract to concrete and connected is the whole technique.
Why are abstract concepts harder to remember than concrete ones?
Because of the concreteness effect, a well-established finding that memory for concrete, easily imagined things is reliably better than for abstract ones. A concrete word like hammer comes with a built-in image and context and is stored through both language and imagery, while an abstract word like justice activates only the verbal system, with no picture to anchor it. The same applies to whole concepts: vivid, concrete ideas stick, and abstract ones slide away, which is why the fix is to make them less abstract.
How does visualization help memorize abstract ideas?
It manufactures the imagery abstract ideas naturally lack. Turning a concept into a picture, even an invented or absurd one, lets you store it through both words and a visual, giving you two routes to recall instead of one. Producing a drawing works even better than just imagining, because making the visual forces you to process the idea. To remember that inflation erodes purchasing power, picture your wallet shrinking as prices balloon; vivid and concrete beats accurate and dull.
Is it better to understand or memorize an abstract concept?
Understand it. For ideas rather than arbitrary facts, understanding is the most reliable form of memory. A memorized definition sits alone, decays fast, and breaks when the wording changes, while an understood concept is robust, because you grasp why it is true and how it connects, so you could reconstruct it even if you forgot the exact words. Trying to brute-force memorize abstractions as definitions is the weakest approach; understanding them through examples, images, and connection makes them stick almost automatically.
Does spaced repetition work for abstract concepts?
Yes, but as the second step, after meaning. Spaced retrieval, recalling a concept from memory at increasing intervals, strengthens memory far more than rereading and is worth using for abstract concepts. The key is order: make the concept concrete and understand it first, then use spaced retrieval to lock that understanding in over time. Drilling a definition you do not yet understand is the ineffective slog most people dread. Understand first, then space the practice.
How do I memorize a concept I find totally abstract?
Force it through concretization. Find a real, specific example from your own life, even a clumsy one, and tie the concept to it. Build an analogy to something you already understand well. Invent a vivid image or quick sketch that captures the idea. Then explain it out loud in your own words and connect it to related concepts. By the time you have given an abstract idea an example, an analogy, an image, and a place in your existing knowledge, it is no longer abstract enough to be hard to remember.
