per-suh-VEER-uhns/ˌpɜːrsəˈvɪrəns/
Continued effort despite difficulty or delay.

Etymology
“Very” and “serious” underlie the idea of earnest firmness, which developed into continuing steadfastly. Perseverance names that constancy as a quality: sustained effort even when progress is difficult or slow.
