Common Mistakes to Avoid
- ✗Assuming 쓰다 always means 'to use' — its meaning depends entirely on context: it can also mean to write, to be bitter, or to wear on one's head.
- ✗Using 사용하다 in casual everyday speech — it sounds overly formal. 쓰다 is more natural for everyday use.
- ✗Writing '사용하다' when you mean 'to write' — 사용하다 never means to write. Use 쓰다 for writing.
- ✗Confusing 쓰다 (bitter) with 달다 (sweet) — these are antonyms describing taste, unrelated to the 'use' or 'write' meanings.
Frequently Asked Questions

Is 이용하다 similar to 사용하다?
Yes, 이용하다 also means 'to use' and is similarly formal. However, 이용하다 often implies using a service or facility (교통을 이용하다 — to use public transport), while 사용하다 is more about using a tool or object.
When would a native speaker choose 사용하다 over 쓰다 in everyday speech?
Native speakers tend to use 사용하다 when giving instructions, writing signs, or in professional contexts. In a casual chat, 쓰다 is almost always more natural for 'use.'
