What does lagniappe mean?

Lagniappe [lan YUP]
means
"a little something extra". It's a Louisiana French (and Trinidadian Creole
English) word, derived from American Spanish la ñapa, and originally meant a
gift given to a customer by a merchant at the time of a purchase, such as a 13th
beignet when buying a dozen. (thanks Wendy) I hope that my blog will deliver
small "gifts" each time you read it
.
