Pro Tip
Usage with particles
같다 is frequently paired with -와/과 (and) or -처럼 (like) to compare things: '저는 형과 성격이 같아요' (I have the same personality as my older brother).
Gold Rule
Same vs. Similar
같다 implies exact sameness, while 비슷하다 means 'similar' but not identical. Use 같아요 for exact matches and 비슷해요 for close but not identical comparisons.
Word Origin
From Middle Korean 갓다 (gatda), derived from Old Korean roots meaning 'to be alike' or 'to match'. The adjective form evolved from the verb form meaning 'to resemble'.
Usage Notes
같다 is often used with particles like -와/과 (and), -처럼 (like), or -같이 (like) to indicate similarity. It can also be used in expressions like '마찬가지예요' (It's the same) to agree with someone.
