Other forms: enduring, endured, endures
To endure is to suffer through something painful without giving up. Endure the pain, endure years of it, hard to endure.
It also means simply to last: the building has endured for four centuries, an enduring friendship. That second sense is the older one and gives enduring, meaning long-lasting. Endurance is the noun and is a technical term in sport — endurance events, endurance training. Note that endure is transitive in the suffering sense and intransitive in the lasting one, which is a neat split.
