Elative (abbreviated ELA; from Latin efferre "to bring or carry out") is a locative case with the basic meaning "out of".
Uralic languages
In Finnish elative is typically formed by adding "sta/stä", in Estonian by adding "-st" to the genitive stem. In Hungarian the suffix "-ból/-ből" is used for elative.
"talosta" - "out of the house, from house" (Finnish "talo" = "house")
"majast" - "out of the house, from house" (Estonian "maja" = "house")
"házból" - "out of house" (Hungarian "ház" = "house")
In some dialects of colloquial Finnish it is common to drop the last vowel and thus the usage of elative resembles that of Estonian, for example "talost".
