Other forms: tiffins
In India, a tiffin is a meal eaten any time between breakfast and dinner. The round metal lunchbox it often comes in is also called a tiffin, and it's a handy container for packing a hot lunch.
During the period of British rule in India, the British custom of afternoon tea merged with the Indian custom of a light afternoon meal. It came to be called tiffin, after the English slang tiffing, "to take a little drink." In Northern India, tiffin is basically lunch, often one packed in a tiered metal lunchbox also called a tiffin. People who sell pre-packed tiffins are called tiffin wallahs or dabbawalas.
