Same means exactly alike or unchanged. When two things are the same, they match in every important way. If you and your friend both order the same lunch, you're eating identical meals. If you wear the same shirt two days in a row, it's the exact shirt, not a different one.

The word appears constantly in everyday speech. You might say “I feel the same way” when you agree with someone's opinion, or “It's all the same to me” when you don't have a preference between choices. When someone says “Same here!” they're expressing that they share your experience or feeling.

Same can also mean boring or repetitive, like when you complain about eating the same thing for dinner three nights in a row. The phrase “the same old, same old” describes a dull routine that never changes.

Be careful not to confuse same with similar. Similar things resemble each other but have differences. Two similar bikes might be the same color but different sizes. Two bikes that are the same match in every important way. When you want to emphasize that something is truly identical and not just close, same is the word you need.
