～さえ

• Reading: さえ
• Romaji: sae
• Formation: Noun + さえ + Predicate (replaces が/を; follows に/で)

Meaning

An emphatic particle meaning 'even,' used to highlight an extreme or unexpected example to emphasize a broader point in non-conditional clauses.

さえ singles out an extreme case to imply that if even this case applies, then everything less extreme certainly applies too. For example, saying 'even a child knows that' implies that absolutely everyone knows it. さえ replaces particles like が and を but follows に and で. It is distinct from the conditional さえ～ば pattern — here it is used purely for emphasis. Compared to も (also), さえ is much stronger and more dramatic, carrying a sense of surprise or unexpectedness.

Examples

1. そんな簡単なことは子供さえ分かる。 Even a child can understand something that simple.
2. 忙しすぎて昼ご飯さえ食べられなかった。 I was so busy I couldn't even eat lunch.
3. 彼女は自分の名前さえ書けなかった。 She couldn't even write her own name.
