Meaning

An adverb meaning 'simply,' 'merely,' or 'just,' used to indicate that something is nothing more than what is stated. It often downplays or limits the scope of a claim.

単に emphasizes that the reality is limited to a simple explanation, often countering an assumption that things are more complex. It frequently pairs with だけ, にすぎない, or のではなく to reinforce the limitation. Unlike ただ, which can mean 'simply' but also 'however' or 'free of charge,' 単に is unambiguous in its reductive meaning. It appears commonly in formal writing, academic prose, and persuasive arguments. The pattern 単に～だけでなく is especially prevalent, meaning 'not simply X but also Y,' and is used to expand a discussion beyond a narrow framing.

Examples

1. 彼女の成功は単に運が良かっただけではない。 Her success is not simply a matter of good luck.
2. この問題は単に技術的な課題にとどまらず、倫理的な側面も含んでいる。 This problem is not merely a technical challenge; it also involves ethical aspects.
3. 単に数字を並べるだけでは、報告書としての説得力に欠ける。 Simply lining up numbers lacks persuasiveness as a report.
