noun
elasticity; resilience; flexibility; adaptability
Refers to both physical elasticity (e.g., of materials) and figurative flexibility or resilience (e.g., of rules, thinking, or systems).
この素材は弾力性に富んでいる。
This material is highly elastic.
His way of thinking lacks flexibility.
Compound of 弾力 (elasticity) + 性 (nature, property). The exact historical derivation is straightforward; the word follows a common pattern for forming abstract nouns in modern Japanese.
