って (colloquial topic marker)

• Reading: って
• Romaji: tte
• Formation: Noun / Phrase + って + Comment

Meaning

A colloquial particle used to introduce or highlight a topic in casual speech. It functions similarly to は but carries a more informal, conversational tone.

って as a topic marker is a casual reduction of the quotative という or the topic particle は, depending on context. It is extremely common in everyday spoken Japanese when bringing up a new topic or reintroducing one. Compared to は, って adds a sense of immediacy or emphasis — it often implies the speaker wants to comment on or ask about the topic. It frequently appears at the beginning of a statement or question: 明日って休みだよね (Tomorrow's a day off, right?). While は is appropriate in all registers, って is restricted to casual conversation and should be avoided in formal writing or polite speech. It can also carry a slight nuance of surprise or seeking confirmation.

Examples

1. 明日って何曜日だっけ。 What day of the week is tomorrow again?
2. あの映画って面白いの。 Is that movie interesting?
3. 田中さんって優しいよね。 Tanaka is kind, isn't she?
