What it means
すなわち means “that is,” “namely,” or “in other words.” It introduces a more precise restatement, explanation, or specific identification of the preceding statement or noun phrase. It is especially common in formal speech, academic writing, reports, and other written contexts, and it often gives the sentence a logical or explanatory tone.
Usage note
すなわち is relatively formal and can sound stiff in casual conversation. Do not confuse it with つまり, which is more common in everyday speech and often presents a conclusion or summary rather than a precise restatement.
