強力

1. Origins, structure, and basic meaning

• Structure: 強力 is read きょうりょく and expresses strong power or effect.
• Basic usage: It applies to physical force in 強力な磁石 and to influential support in 強力な支え.

2. Common pitfalls and similar expressions

• Before a noun
  • Use 強力な before a noun. Although its meaning overlaps with the い-adjective 強い, it does not inflect as 強力い.
• Same reading
  • 協力 is also read きょうりょく, but means cooperation. Distinguish it from 強力, which describes strength.
