数々

1. Origins, structure, and basic meaning

• Structure: 数々 (かずかず) is a quantifying expression that modifies a noun with の to indicate many items or kinds.
• Basic usage: 数々の困難 groups the many difficulties encountered on a journey, while 数々の品 groups numerous objects collected by a grandfather.

2. Common pitfalls and similar expressions

• Multiplicity without an exact number
  • 数々の emphasizes multiplicity in both examples but provides no exact count. It modifies 困難 and 品 rather than functioning as a specific independent number.
