タイムライン

• Reading: タイムライン
• Romaji: taimurain
• Kanji breakdown: From English 'timeline'
• Pronunciation: /ta.i.mu.ra.in/

Meaning

Timeline or feed — the scrolling stream of posts displayed on social media platforms like Twitter/X.

タイムライン refers to the main page of posts that users see when they open a social media app. On Twitter/X, it is the primary view showing posts from people you follow. The abbreviation TL is also very common. Japanese users often describe the 'mood' of their timeline — for example, 'TL is peaceful today' or 'TL is chaotic' — treating it almost like a shared space with its own atmosphere.

Examples

1. タイムライン見てたら1時間経ってた。 I was scrolling my timeline and an hour just flew by.
2. 今日のタイムラインはニュースばっかりだね。 My timeline is nothing but news today.
3. タイムラインに流れてきた動画がめっちゃ面白かった。 A video that popped up on my timeline was super funny.

Don't Say

Common Mistakes
