"Jeder trinkt dieses Wasser."
I'm very confused by this, it would be the same as saying "Everyone drink this water" which is different than "Everyone drinks this water" which is what is implied.
How can Everyone be singular? Is this some form of grouping at work? If it's grouping, then why doesn't this also apply to You (plural) or They, or Them?
The pronoun "everyone" is decidedly singular across most languages, even though it sounds like it refers to multiple people. The usual explanation is that this is for consistency with "someone" and "no one," which are more obviously singular, but I choose to just regard it as one of the irregularities that arises in language.
Even in English we say everyone drinks, not everyone drink. Same deal in German.
Hope this helps.
@theycallmezeal, funny, the more you learn another language the more you realize you don't yet understand your own. :P
'I' is singular, but it's also "drink", and now I've completely lost all understanding of English. :P
Still though, the idea of "everyone" being singular is a bit of a mind-bender. :P
"Basically rephrasing what SlowLarry said above, it is my understanding that "this vs. that" is not really an issue to concern yourself with. In English, we are using "this / these" to be close to us and "that / those" to be farther away. Typically, if I wanted to describe THE specific computer that is a distance from me, merely referring to it as "Der Computer da" (the computer there) should be sufficient. Since modern spoken German is not particularly concerned with the distance, let us focus on "this or these." "This or these" merely differentiates between singular and plural, so... The: Sing.--Plural Der: Dieser-Diese Die: Diese-Diese Das: Dieses-Diese Notice that it simply mimics the last-letter changes of definitive articles (der, die, das) from singular to plural in nominative case, except the beginning is "dies-". Hope this helps! Examples: Dieser Tisch - Diese Tische = This table - These tables Diese Frau - Diese Frauen = This woman - These women Dieses Spiel - Diese Spiele = This game - These games"
"Alles" means "everything" so you probably meant "Alle" which means "all/everybody". Anyway, I'd also like the answer to this question. If I were to take an educated guess, though, I would say it would read, "Alle trinken dieses Wasser." The reason I would use "trinken" is because you can substitute "all" for "they", right? Or do I have this twisted?
In that case, the verb is a command, or the imperative case, so you would have to think about it differently.
I think that's in a different module, but here's a small explanation: http://www.jabbalab.com/blog/1516/commands-in-german-imperative
