Since just the other day I wrote a post about the difference between 忘れた and 忘れてた, I was trying to think of other easily avoidable mistakes that I’m always making when I speak Japanese.

Then, I totally remembered: I often say 覚えた (おぼえた / oboeta) when I should say 思い出した (おもいだした / omoidashita).

The Difference Between 覚える and 思い出す

If you look at a Japanese-English dictionary, it’s pretty easy to see why this mistake is so easy to make:

覚える (おぼえる / oboeru) to memorize; to commit to memory;to learn by heart; to bear in mind;

to remember

思い出す (おもいだす / omoidasu) to recall; to remember

Okay, so that’s not any help at all.

Let’s look at the following situations in English, and you can see if you can guess which word we would use, 覚える or 思い出す…



A: kare no namae wa nan dakke?
B: ah! Takeshi da! ima ______________!

A: What’s his name again?
B: Ah! It’s Takeshi! I just remembered.



A: kare no namae wa nan dakke?
B: saa… zenzen _________________nai.

A: What’s his name again?
B: Who knows. I can’t remember at all.

The answer’s would be:

1. 思い出した (おもいだした / omoidashita)
2. 覚えて(ない) (おぼえてない / oboete nai )

The first one is 思い出した, because you were just able to pull out (出す / dasu) the information that was previously entered (覚えた / oboeta)the first time you learned Takeshi’s name.

How to Remember the Difference

I think this is a fairly easy difference to distinguish. First, let’s look at 覚える.

覚える / おぼえる / oboeru

覚える can mean “to memorize,” because to 覚える is to put stuff into your brain, put simply.

tango wo oboeta.
I memorized the [vocabulary] word.

In a very similar way, it can also mean to remember. If you think about memorizing, it just means to store information in your brain, which is kind of the same thing as “remembering,” no?

The tricky thing here is that it is possible to say 覚えている for a thing that you still remember.

For example, taking the conversation from above.


A: kare no namae wa nan dakke?
B: ore wa oboeteru yo
A: ja oshiete yo

B: oshienai

A: What’s his name again?
B: I remember it.

A: Then tell me what it is!
B: Nope.

In this example, Person B can say 覚えてるよ, because he has not forgotten Takeshi’s name. It is well organized into his brain, much as though he memorized it. This is different from the Person B we saw earlier, who did not memorize it properly, so he had to work to pull it out (思い出す)of his brain.

思い出す / おもいだす / omoidasu

This trick to remembering how to use 思い出す is that you can say it whenever it would be okay to say “to recall” in English. By doing this, you can also say that you “don’t recall.”

For example, we could put a spin on #2 from above…


A: kare no namae wa nan dakke?
B: nan dakke?! omoidasenai!

A: What’s his name again?
B: Ah, what was it?! I can’t remember! [=I can’t recall.]

Remembering… recalling… memorizing… sounds like trying to learn a language.

Anyways, does that make sense? If not, please let me know in the comments. Also, let’s look at one nasty example from Waeijiro 140…

思い出せないものは三つしかないんだ, 人の名前が覚えられない, 顔が覚えられない, それに,三つ目が何だったかが思い出せないんだ
omoidasenai mono wa mittsu shika nainda, hito no namae ga oboerarenai, kao ga oboerarenai, sore ni, mittsume ga nan datta ka ga omoidasenai nda.
There are only three things I can’t remember — I can’t remember names; I can’t remember faces; and I can’t remember what the third thing is.

[Wow, that one might be difficult. If you really think about it, though, it makes sense according to the explanation above.]

Good luck with your studies, everyone.
