It is based on about 5 different vocabulary frequency lists and my personal word lists which contain words that were occurring organically when I was learning languages from scratch or improving the languages I knew (Persian, Serbian, Polish, Cantonese, Spanish, Hungarian, French). This list contains only the most important nouns from all of these lists, that give you most language coverage, re-arranged so that they would roughly be ordered from the most useful, most general ones downwards.
I also worked on English, Spanish, Italian, French, Romanian, Portuguese, German, Mandarin Chinese (simplified and traditional), Russian (Cyrillic and Latin), Slovak, Hungarian and a Romance combo noun frequency list.
