Since "The Norwegian" is reffered to as a people, should it not be "The Norwegian read...."?. The right solution comes out as "The Norwegian reads...". I am sorry that this is actually a question about english grammar, but I would like to help improve Duolingo corrections (as well as my own knowlege) :) Thank you in advance.
Yes, but not 'the Norwegian'. 'The British' and 'the French' are the plural forms, but 'the Norwegian' isn't plural. You cannot say 'the Norwegian read books' (where read is present tense). I think it's to do with the ending: -ish is unchanged in the plural, but -an requires an s. For example, you can say 'the Spanish are...' or 'the Swedish are...', but not 'the German are...' or 'the Italian are...'. You have to say Germans or Italians. The -ese ending doesn't change in the plural either e.g. 'the Chinese are...'.
