+Well ordering is a property where every non-empty subset of an ordered set contains a unique minimum element. It forms a cornerstone of [Order Theory](/wiki/order_theory) and is crucial for rigorous proofs like those using [Transfinite Induction](/wiki/transfinite_induction). This concept grants any subcollection a definitive "first" element.
