How to use it

Two factors resonate together, producing an effect greater than either alone. Formal writing.

  • 「AがBと相まって、C」 = A combines with B to produce C. C is a notable result, usually positive or striking.
  • The core idea is RESONANCE, not simple addition: the two factors interact so the result exceeds expectations.
  • The form 「AとBが相まって」 also appears when stating both as the subject together — 「努力と運が相まって、成功につながった」.

Examples

  • Effort combined with luck led to success.

  • The scenery combined with the music left a deep impression.

Keep in mind

  • The particle is 「と」: 「Bと相まって」, not 「Bに相まって」.
  • Written style (articles, commentary); conversation usually says 「~も手伝って」.

Common mistakes

  • Wrong努力(どりょく)に相(あい)まって成功(せいこう)した。

    Correct努力(どりょく)と運(うん)が相(あい)まって成功(せいこう)した。

    Combining factors uses と相まって.

Exam tips

  • 「と相まって」 = resonating together with (uses 「と」); formal writing, an outstanding result.
