そもそも（の）

• Reading: そもそも
• Romaji: somosomo
• Formation: そもそも + Clause / そもそもの + Noun

Meaning

An adverb meaning 'in the first place' or 'to begin with,' used when the speaker questions or comments on the fundamental premise of a situation. With の, it functions as a noun modifier meaning 'fundamental' or 'original.'

そもそも directs attention back to the root or origin of an issue, often implying that the current discussion or approach has strayed from something essential. It frequently carries a critical or corrective tone — the speaker suggests that a fundamental point has been overlooked or that the premise itself is flawed. When followed by の and a noun (そもそもの原因, そもそもの目的), it functions as a modifier meaning 'the original' or 'the underlying.' そもそも can introduce a rhetorical question or a statement that reframes the entire discussion. It appears across registers, from casual conversation to formal debate, though it is especially common in argumentative and analytical contexts.

Examples

1. そもそも、この計画には無理があったのではないか。 Wasn't this plan unreasonable in the first place?
2. そもそもの発端は、部署間の連携不足にあった。 The root cause lay in the lack of coordination between departments.
3. 予算の議論をする前に、そもそもこの事業を続ける意義を問い直すべきだ。 Before debating the budget, we should reconsider whether there is any point in continuing this project in the first place.
