って

The particle って is a casual particle used extensively in spoken Japanese. It serves multiple functions depending on context: quoting speech, indicating something is "called" or "named," marking a topic (like a casual は), and conveying hearsay. It is informal and typically found in conversation rather than in writing or formal contexts.

Casual quotation (replacing と)

って can replace the quotation particle と before verbs like ゆう言う, おもう思う, きく聞く, etc. It marks what someone said or thought.

The quoting verb (言う, etc.) can be omitted entirely, leaving って at the end of the sentence to imply "someone said" or "I heard."

"Called" or "named" (replacing という)

って can replace という when indicating the name or identity of something.

Casual topic marker (replacing は)

って can function as a casual topic marker, similar to は. It brings up a topic and often carries a nuance of "speaking of" or "when it comes to."

This usage is especially common when introducing a topic for discussion or asking about something.

Repeating or emphasizing what was said

って can be used to repeat or insist on something you've already said, often with a tone of mild frustration or emphasis.

Key points

• って is informal. In polite or written contexts, use と, という, or は instead.
• When って appears at the end of a sentence with no following verb, it typically conveys hearsay ("I heard that…" / "they say…").
• When って marks a noun or topic at the beginning or middle of a sentence, it functions as a topic marker or means "called."
