相乗

そうじょう
noun
synergy; mutual amplification
1. synergy; mutual amplification
Two or more factors reinforcing one another so that their combined result exceeds the simple sum. Almost always used in compounds, above all 相乗効果(そうじょうこうか).
二(ふた)つの薬(くすり)で相乗効果(そうじょうこうか)が生(う)まれる。
The two drugs produce a synergistic effect.
広告(こうこく)と口(くち)コミが相乗効果(そうじょうこうか)を発揮(はっき)した。
Advertising and word of mouth produced a synergistic effect.
二(ふた)つの政策(せいさく)が相乗(そうじょう)して経済(けいざい)を押(お)し上(あ)げた。
The two policies worked synergistically to lift the economy.

Literally "mutual multiplication." Distinct from 相加(そうか) (mutual addition); a synergistic result is multiplicative rather than merely additive. Used almost exclusively inside compounds.
