Elative is a locative case with the basic meaning "out of".
In Finnish elative is typically formed by adding "sta/stä", in Estonian - "st" to the genitive stem. In Hungarian suffix "ból/ből" is used for elative.
"talosta" - "out of the house, from house" (Finnish)
"majast" - "out of the house, from house" (Estonian)
"házból" - "out of house" (Hungarian)

The term elative can also refer to the form of an adjective or adverb that indicates a global maximum, e.g. "the most beautiful woman on earth". Although the meaning differs from that of the superlative, both forms look identical in English. Other languages might use different inflection rules.
