「もの・もん」の情報

もの, an extremely common noun in Japanese that means 'thing', can also be used as a sentence ending particle. In these cases, it adds a small amount of emotion to a statement, and presents it as a reason. Due to this, もの is usually translated as 'because', or 'cause'. Literally, it just means 'it's an (A) thing!'. もの is quite casual, so should be avoided in formal situations.

To use もの as 'because', attach it to the end of the plain form of any word.

To emphasize もの even further, the explanatory んだ (after a verb or い-Adjective), or なんだ (after a な-Adjective or noun) will often be used.

Caution

もの can be shortened to もん in its use as a sentence ending particle. However, this makes the statement sound far more 'cute' or 'childish'. Due to this, it should be avoided in standard conversation.

Fun Fact

Although it is not used regularly in standard Japanese, んですもの is a slightly more polite version of んだもの that appears frequently in anime, manga, and novels.
