「によって・による」の情報

によって, による, and により are all different versions of the same expression, that can basically be translated as 'according to (A)', or 'depending on (A)'. This uses the same よる as seen in the grammar pattern によると. They will be used in the following way:

によって - Generally used before a comma (although not always). Acts as the separation point between the (A) and (B) parts of a sentence. Made up of the case marking particle に, and the う - Verb よる in its て form.

による - Generally used at the end of a sentence, to highlight that the previous statement depends on (A).

により - Almost always used before a comma. Acts as the separation point between the (A) and (B) parts of a sentence. Made up of the case marking particle に, and the う - Verb よる in its conjunctive form.

To use any of these constructions, attach them to the end of a noun that you want to express as being the 'dependent' thing.

Caution

による may also sometimes be followed by a noun. In these cases, it will become a verb modified noun, and highlight that (B) resulted from (A).

Fun Fact

Although よる is almost always written in hiragana, there are several different kanji that use this reading. They all share similar meanings. Learn more about this in the によると grammar point.

    Rather than an exclusion or new use, it’s really just a use of the grammar point.

    “It was made by the means of” becomes the basic meaning!

    Sorry for the late reply on this one! In general, regardless of the grammar point, the difference between the て form and the base form of a verb is how it interacts with the rest of the sentence. Basically, the difference is as follows.

    (A) 〜て (B)

    (A) is not directly linked to (B), but sets the precedence for further explanation. For example よく走って、健康になる ‘Run often and get healthy’. Using the same logic with によって, 教師によって、授業の内容が変わる ‘Depending on the teacher, the content of a class will change’. (B) elaborates on (A)'s setup.

    (A) る (B)

    (A) is directly linked to (B), so becomes an extension of it. For example よく走る人 ‘A person that often runs’. Using the same logic with による, 天気によるもの ‘something that depends on the weather’. (B) is the main focus and (A) is just an explanatory statement.
