幾分

1. Origins, structure, and basic meaning

• Structure: 幾分 is an adverb read いくぶん, meaning somewhat or to some degree rather than completely.
• Basic usage: It modifies a change, as in 幾分和らぐ for easing somewhat and 幾分明るくなる for becoming a little brighter.
  • 風が弱まり、寒さも幾分和らぎました。 says that as the wind weakened, the cold eased somewhat; 説明を聞いて、彼の表情は幾分明るくなりました。 describes his expression brightening a little after the explanation.
