A word ladder is a word game where players transform one word into another by changing one letter at a time, with each step resulting in a valid word. The goal is to change the starting word into the target word in the fewest possible steps. For example, changing "cold" to "warm" might involve steps like "cold" to "cord" to "ward" to "warm." Word ladders are designed to challenge vocabulary, spelling, and thinking skills, and they are often used as a fun exercise for both language learners and puzzle enthusiasts.
