Multiplicative case

The multiplicative case (abbreviated ' or ') is a grammatical case used for marking "a number of something" ("three times"). 
The case is found in the Hungarian language, for example "nyolc" (eight), "nyolcszor" (eight times), however it is not considered a real case in modern Hungarian linguistics because of its adverb-forming nature.
The case appears also in Finnish as an adverbial (adverb-forming) case. Used with a cardinal number it denotes the number of actions; for example, "viisi" (five) -> "viidesti" (five times). Used with adjectives it refers to the mean of the action, corresponding the English suffix "-ly": "kaunis" (beautiful) -> "kauniisti" (beautifully). It is also used with a small number of nouns: "leikki" (play) -> "leikisti" ("just kidding", "not really"). In addition, it acts as an intensifier when used with a swearword: "piru" -> "pirusti".
