Kara for Reasons: Explain Why

Reason から follows a proposition and connects it to a result, decision, or request. In 雨ですから、行きません, rain is the reason for not going. This use differs from a starting point such as 九時から and from the sequence pattern てから.

Formation and use

Verbs and i-adjectives can use plain forms: 行くから, 寒いから. Nouns and na-adjectives need だ in the basic plain affirmative: 学生だから, 静かだから.

Polite forms can precede から: 忙しいですから, 行きますから. The level of politeness depends on the whole sentence and setting; plain embedded forms can also appear with a polite final predicate.

Comparisons and common errors

から can support a request or suggestion: 危ないですから、入らないでください. The speaker gives a reason for the requested action. A blunt delivery can still sound forceful.

なぜ or どうして can ask for a reason. A short response may end in からです, as in 忙しいからです. In longer explanations, connect the reason to what it explains rather than leaving an unclear fragment.
