In Japanese, I have encountered 3 words for selecting or making a choice (so far).



He chose a good wife.



Nevertheless, many are choosing early retirement.



The choice of example sentence wasn't wise.

(Sample sentences are from JDIC:ED)

Are there any differences between the three? Or are they generally interchangeable?

Your first example is 選{えら}んだ, which is from the verb 選ぶ. It's the Japanese-origin word for "choose" and differs mostly by its formality compared to Chinese-origin words.

選択 is a simple choice. Pick a card, pick your classes, choose an answer on a test, or, as in your example, choose early retirement.

選定 is a choice with purpose. You choose something to match a set of criteria. You look at the choices, judge them each, and make the decision with regard to what you feel is the most appropriate one. For example, 議員を選定する. An example here is "購入機種の選定会議." It has more of an "official" flavor and is quite formal. It might be helpful to think of it as something that goes through a selection process. On the site I mentioned previously, a key distinction in the descriptions is in the choice of words for the actual verb: with 選択 it uses 選び出す, but with 選定, it uses 決める. This reinforces the idea of one being a mere choice while one is more elective. I'm sorry if this explanation is hard to follow but I'm straining to explain what is essentially in English the difference between choose and choose.

You asked separately why you would not use 選定 for an answer on a test. Think of it this way. When you're choosing answers on a test, you may be weighing each choice against certain conditions, but ultimately you're not really "deciding" which one is best. You're deliberating which one seems like the right answer. But your choice could be wrong. Because of the correct/incorrect nature you're choosing an answer in the lightest sense of the word, no matter how hard you think about it. With 選定 it's more about choosing one of several valid options and making a decision about which is most appropriate. For example, if you were to use 選定 on a test question, it would sound to me like you were choosing a test question or answer to be used as a representative or some kind in some compendium of example test questions and answers, trying to decide which ones to include in the collection.

It should be clear, then, that 選択 and 選定 are not interchangeable. 選ぶ on its own is not formal at all and can be kind of excluded on that basis, though you can probably use it (with the right level of formality) to mean the same thing as the other two. 選択 is for things where the judgment and criteria aren't as important as the act of choosing in itself, while 選定 emphasizes the meaning and purpose behind a choice.

  • ssb you say that 選択 is for choosing an answer on a test and later 選定 when you "You look at the choices, judge them each, and make the decision with regard to what you feel is the most appropriate one." On a test, isn't that exactly what you do? choose the most appropriate one? So why not 選定?

  • (1) It is not clear to me why 選ぶ and 選択する are not interchangeable for meaning. (2) How do we know 選定 is actually in your active vocabulary? Your explanation is only a translation of what an online monolingual dictionary states.

    1. I meant 選択 and 選定, I should have said that explicityle. (2) Why does it matter if 選定 is or isn't in my active vocabulary? Yes, it might be shocking to know that as someone who's not a We Native Speakers I find it useful to check a dictionary from time to time to make sure I have the nuances worked out right, but this is not a concession that I have no idea what I'm talking about. Let my answer stand on its own and don't try to judge it based on your perception of how good I am at Japanese. If there's something wrong in it, feel free to leave constructive comments telling me where.
