これ, それ, あれ: The こそあど System That Makes ‘This’ and ‘That’ Make Sense

Almost every beginner hits a quiet moment of confusion here. You learned これ means “this.” Then you see この and assume it is a typo or a synonym. Then あれ and それ both look like “that.” English only has two pointing words, so a three-way system with parallel sets feels like too much. It is not. It is a grid, and once you see the grid you never guess again.

The Two Dimensions

Every word in this family is built from two parts. The first part (こ / そ / あ / ど) encodes distance. The second part encodes grammar: what the word does in a sentence.

This is the part English cannot do in single words. それ is not just “that” in general; it is “that, near you.” あれ is “that, far from both of us.” The distinction is built around the two people in the conversation.

The Full Grid

Now attach the endings. れ makes a standalone pronoun, の attaches to a noun, こ marks a place, んな describes a kind.

This single grid is the entire system. Learn the four columns and the four rows and you have unlocked sixteen high-frequency words at once. That is an enormous return for one table.

The これ vs この Trap

The most common mistake is using これ where この is needed. The rule is simple: これ stands alone, この must be glued to a noun.

If you can replace it with “this one” on its own, use これ. If you would say “this [noun],” use この. Saying これ本 is exactly the error that sounds off to a native ear, and this one rule removes it forever.

Distance in Action

Picture two people talking. The umbrella in your hand is これ. The one next to the other person is それ. The one across the room is あれ. The system is a map of the conversation space.

The そ- Words Also Point Backward

そ- has a second, very common job: referring to something already mentioned, even if nothing is physically nearby. This is huge for natural conversation and reading.

Here それ is not pointing at a physical object; it points back to something in the discourse. This contextual それ is how Japanese avoids repeating nouns, and recognizing it is key to following longer passages.

How to Make the Grid Reflexive

The こそあど system rewards pattern learning, because every word shares structure with fifteen others. That is the ideal target for spaced, contextual review, and it is exactly how Kanjijo teaches it. Each word appears inside example sentences that make the distance concrete, exclusive mnemonics anchor the こ/そ/あ/ど roots so you never confuse the columns, and SRS resurfaces the tricky これ-versus-この distinction right before you forget it. Reading practice trains you to catch the backward-referring それ in real text, listening practice tunes your ear to these high-frequency words, the OCR scanner lets you decode この and その on real signs and labels, home and lock screen widgets surface a demonstrative during dead moments, and mock JLPT questions test the grid under pressure. The sixteen words stop being a list and become one clean instinct.
