Many learners confuse “capital” and “capitol” because they look almost identical. The only difference is one letter: “a” vs “o.” But that small change creates completely different meanings.
This confusion is very common for students, ESL learners, and even native speakers. The good news is that once you learn one simple trick, you will never mix them up again.
Quick Answer
- Capital = city, money, or uppercase letter
- Capitol = a government building
Examples:

Simple Background Explanation
