endurance
UK: ɪnˈdjʊərəns | US: ɪnˈdʊrəns
n. the ability to withstand hardship or adversity
n. the capacity to sustain prolonged physical or mental effort
n. persistence over time
The word "endurance" derives from the Old French "endurer" (to harden, bear, tolerate), which itself comes from Latin "indurare" (to harden, make firm). The Latin roots are "in-" (intensive) + "durus" (hard). Over time, "endure" evolved in English to mean "to last" or "to bear patiently," and the suffix "-ance" was added to form a noun describing the quality of lasting or persevering. The logic reflects a metaphorical hardening—like metal tempered to withstand stress.
