Japanese Abbreviations, Slang

Like in any language, Japanese may not speak very clear ... they make words shorter:

polite and clear

... する の です = ... SURU NO DESU
= "As a matter of fact, ... (somebody) is doing"

shortened

... する ん です = ... SURU N DESU

... する ん だ = ... SURU N DA

... す ん だ = ... SU N DA

... す ん じゃ = ... SU N DJA

The shorter, the less polite!

polite and clear

なん です か= NAN DESU KA

なん す か= NAN SU KA
= "What´s this?"

なん か= NAN KA
= "Huh ... What´s that?"
