John G. Hocking and Gail S. Young’s Topology is a classic first course that builds the foundations of point-set topology with clarity and many worked examples. Beginning with sets, continuity, and topological spaces, it develops core ideas such as connectedness, compactness, product and quotient constructions, and separation axioms. The exposition balances rigor with intuition, using geometric motivation and plentiful exercises to train technique. Widely used for decades (now in a Dover reprint), it remains a reliable, self-contained text for advanced undergraduates and beginning graduate students.
