Korean Speech Levels: ~요 vs. ~법니다/습니다 — Which One for Your Diary?

Both ~요 and ~법니다/습니다 are polite, but they feel very different. Here’s which one to use for your Korean diary — and why consistency matters.

When you start writing in Korean, one question comes up almost immediately: should I use ~요 endings or ~ㅂ니다/습니다 endings?

Both are polite, but they feel very different — and the wrong choice can make your writing sound stiff or out of place.

The Quick Difference

StyleEndingFeels Like
Polite informal~요Friendly, personal writing
Formal~ㅂ니다/습니다Presentations, official documents

Example:

  • 오늘 날씨가 좋아요. (Polite informal — natural for a diary)
  • 오늘 날씨가 좋습니다. (Formal — sounds like a weather report)

For Diary Writing: Use ~요

A diary is personal. You are writing to yourself, reflecting on your day. The ~요 style matches that tone — warm, conversational, and natural.

~ㅂ니다/습니다 is not wrong, but it creates distance. Reading your own diary in formal speech feels like reading a memo to yourself.

One Tip Worth Remembering

Many learners mix both styles in the same entry. Pick one and stick to it. Consistency makes your writing feel more natural and helps build good habits faster.
