〜さえ〜ば

sae ba

By Nihongo PathUpdated

Meaning

"if only ~", "as long as ~" — one condition is all that is needed.

さえ isolates the one thing that matters, and the ば-clause makes it the condition. Everything else is irrelevant.

Saying that a single thing would be enough, often with a touch of regret (〜のに).

Formation

V = verb, N = noun, A = adjective.

  • N + さえ + V-ば
  • V-ます stem + さえ + すれば
  • V-て + さえ + いれば
  • い-adj stem + く + さえ + あれば
  • な-adj / N + で + さえ + あれば

    "As long as (a state continues)": 生きている限り.

Common mistakes

    ✓
    薬を飲みさえすれば
    Why
    Verbs attach with the ます stem before さえすれば.
  • ✗
    安いさえあれば
    ✓
    安くさえあれば
    Why
    い-adjectives use the く-form before さえあれば.
  • ✗
    お金さえあったら、何でも買える。
    ✓
    お金さえあれば、何でも買える。
    Why
    The pattern uses the ば-form; たら is not standard here.

Emphasizes that nothing else is needed. Compare 〜ば (neutral condition). Negative: 〜さえ〜なければ. Very often paired with a positive result or a wish (〜ば〜のに).

JLPT N3 tips

On the exam

  • さえ before the blank and a result clause after = the blank is a ば-form (あれば, すれば, いれば).
  • Match the verb form: ます stem + さえすれば, て-form + さえいれば. Wrong stems are the trap.
  • For "if only… hadn't", the pattern is さえなければ.
