1. and so on; etcetera; and more
A casual emphatic repetition of など, used at the end of a list to indicate that there are more items. More emphatic and conversational than a single など, suggesting that the list could go on considerably.

Apples, bananas, oranges, and so on.
Cooking, cleaning, laundry, and so on — there's a mountain of things to do.
With travel preparations — checking my passport, booking a hotel, packing, and so on — there's so much to do that it's overwhelming.

Usage

More casual and emphatic than a single など or (など). Often used in spoken Japanese and informal writing. Implies that the speaker could continue listing items but chooses not to. Can convey a sense of being overwhelmed by the quantity.

Similar words

  • など: The basic form, neutral in register. Can be used formally.
  • 等々(とうとう): The formal/written equivalent of などなど. Used in documents and formal speech.
  • : Casual particle for listing examples, but used between items rather than at the end of a list.

Register

Conversational and slightly playful. Not appropriate in formal writing or business documents, where (とう) or 等々(とうとう) would be preferred.
