== 'Nederlands' does not mean 'Of the low countries'  == 

 I am a native of Dutch, and indeed, while 'Nederland', the name of our country which means 'Low Country' is a neuter noun and most likely has its (nowadays archaic) genitive on 'Nederlands', most likely. The term 'Het Nederlands' as a use for our language is an adjectivial noun. That it is 'Het Nederlands' as opposed to 'Des Nederlands' shows this, as 'des' is the (again, archaic) neuter genitive article versus nominative 'het', as Dutch often puts neuter definite articles before adjectives transforming its meaning into the name of a language cf 'een Engels huis' (an English house) 'Het Engels' (The English Language). Also the most potent indication that most surely it is not a genitive is that the -s suffix on a lot of adjectives which descents from archaic Dutch -sch cf En '-sh', M.En, '-sch', Ger '-sch', Engels, archaic: Engelsch (English). A better translation would quite simply be 'Low-Countrish', or less awkward an English phrase: 'Low-Landish'
