「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.

- あなたが言う事は何も信じられないわ。だって、あなたはいつも嘘をつくもの。I can't believe anything you say. Cause you always lie.
- だって、彼女が悪いんだもの。Cause she is the one in the wrong.
- これはあなたにあげられない。大切だもの。I can't give this to you, cause it is important.
- すぐ泣くに決まってるじゃん、まだこどもだもの。Of course he will cry, cause he is still a child.
- エアコンをつけて寝ているよ。だって、暑くて寝れないんだもの。I sleep with the A/C on. Cause it's so hot that I can't sleep, you see.
- この子は失敗するに決ってるでしょう、まだ新人なんだもの。Of course this kid will make mistakes. Cause he's still new here.
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.- もうお腹いっぱいだもん。Cause I'm already full.
- いいよ、お前とはもう遊ばないもん!It's all good! (Because) I'm not going to play with you anymore! (Showing mild anger/jokingly)
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.- こんなものすぐに壊れるに決まっているじゃないですか、紙から出来てるんですもの。Of course something like this will break instantly. (Because) it is made of paper.
- しょうがないですよ、あの人は何も考えていないんですもの。We can't help it. (Because) that person doesn't think about anything.

The Information section of the grammar page needs to be cleaned up. The words “because” and “cause” are not the same meaning. When “because” is shortened in casual conversation, an apostrophe is used to show the contraction:
do not → don’t
should not → shouldn’t
because → 'causeWithout the contraction apostrophe, the word “cause” is a different meaning.
