natural; as a matter of course

📖 How to use it

Expresses that something is natural, expected, or a matter of course.

Attaches to Attach to the て-form of a verb: 動詞て形 + 当然だ. For nouns and な-adjectives, use で当然だ (e.g., 学生で当然だ). For い-adjectives, use the て-form of the adjective (e.g., 若くて当然だ).

This pattern states that an action or state is the natural result of the situation, like saying 'it's only natural that...' or 'of course...' in English. It often carries a sense of inevitability or justifiability. For example, if you study hard, it's natural to get good grades. If someone is a professional, it's natural they are skilled.
