もの・もんBecause, Cause

ので expresses a cause or reason, similar to 'A, so B' in English. もの or もん (the latter being more casual) can also express a reason, adding emphasis or emotion, like the English 'because.' The main difference is that ので sounds more objective and can be used mid-sentence, while もの or もん typically comes at the end of a sentence and conveys a more personal or emotional tone.

から expresses a cause or reason, similar to 'A, so B' in English. もの or もん (with もん being more casual) can also express an emphatic or emotional reason, similar to 'because' in English. The main difference is that から can be used mid-sentence, while もの or もん typically appears at the end of a sentence and conveys a more personal or emotional tone.

Both もの・もん and ことだから can be used to give reasons, but they differ in tone and intent. もの・もん is casual, colloquial, and subjective, used to express personal feelings or justifications, like 'because (A)'. ことだから, on the other hand, has a more objective and emphatic feel, often meaning 'it is precisely because (A) that (B)'. In some contexts, ことだから can also imply 'considering (A), then (B)'.

These two are closely related and use the same もの (with もん as a more casual variant) to express reason. もの・もん is often used at the end of a sentence in a casual or even childish tone to give a personal reason, e.g. 'because (A)'. ものだから is a slightly more formal expression, often used to explain or justify an action or situation in a softer, less direct way.

These expressions also share the same root as もの・もん, but differ in tone and formality. もの・もん is casual and subjective, typically used for personal justifications like 'cause (A)'. ものですから or もので adds a more objective or polite tone, and is commonly used in formal or semi-formal situations when offering explanations or justifications for one's actions or circumstances.

なぜなら〜から and もの・もん are similar in that both can express a reason, but they differ significantly in tone and formality. なぜなら～から is a formal and objective way of stating a reason, similar to saying, 'as for why, it is because (A)'. In contrast, もの・もん is casual or colloquial, sometimes even childish, and conveys a personal, subjective tone, like saying, 'because' or ''cause (A)'.
