〜ことから

About

〜ことから is a formal piece of grammar that is most commonly used in written contexts, or formal spoken contexts (e.g. the news) and generally translates to "Based on the fact that/From the fact that/Due to the fact that...".

〜ことから can attach directly to verbs/い-adjectives, or to な-adjectives/nouns using である or の・な.

〜ことから attaches to information that is based on established realities, or facts.

E.g. バナナを投なげてきたということから、警察けいさつは、ただの嫌いやがらせと断定はんていした。 "Based on the fact that they threw a banana, the police determined that it was merely a prank."

E.g. 顔かおがとても似にているし、服ふくも同おなじであることから、双子ふたごだと思おもわれる。 "Due to the fact that their faces are similar, and their clothes are the same, it is thought that they are twins."

E.g. メールがいつも丁寧ていねいなことから、親切しんせつな人ひとだと思おもっていたが、そうでもなかった。 "Based on the fact that their emails are always polite, I thought that they were a kind person, but that wasn't the case."

〜ことから statements often end with verbs such as: と言いわれる "It is said that", と判断はんだんする・される "(someone) determines/it is determined that", と呼よばれる "Something is called", と考かんがえれる "It can be thought that".

～ことから shouldn't be followed by volitional statements, wants, requests, or desires.
