も当然だ【もとうぜんだ】

The grammar pattern も当然だ expresses that something is only natural, no wonder, or perfectly understandable given the circumstances. It conveys the speaker's judgment that a certain outcome or feeling is completely expected and reasonable.

Basic Usage

も当然だ attaches to a verb or clause (often in plain form) to indicate that the result or reaction described is a natural consequence.

The pattern typically takes the form Verb (plain form) + のも当然だ, where の nominalizes the preceding clause. It can also appear as も当然のことだ for added emphasis.

Nuance

This pattern carries a strong tone of empathy or agreement with the situation described. The speaker acknowledges that given the context, the outcome makes perfect sense. It can be used to sympathize with someone's feelings or to justify a result.

Polite and Casual Forms
