〜さえ〜ば (sae ~ ba)

JLPT N3

How to say “as long as (just) ~, then …” — one condition is all you need.

Meaning

“If only ~ / as long as ~.” Highlights the single condition that's enough for the result.

Formation

• Noun + さえ + [verb ば-form]

• Verb (ます-stem) + さえすれば

• い-adj: 〜く + さえあれば; な-adj: 〜で + さえあれば

Examples

お金さえあれば、世界中を旅行できる。

ボタンを押しさえすれば、動きます。

静かでさえあれば、部屋は狭くてもいい。

How it works

さえ picks out the one crucial condition and ば/なら gives the result — “nothing else matters, just this.” It shows a single requirement is sufficient.

Compared with similar expressions

• 〜ば — if (a condition, no “only” nuance).

• 〜たら — if / when (specific situation).

Common mistakes

• Verb: ます-stem + さえすれば: 押す → 押しさえすれば

• Don't drop the ば/なら half — さえ alone isn't the full pattern.
