Das Kind is refered to as an object (it) ?? ES?!
Not really an object, just neuter; the same way as der Mond (the moon) isn't really male, just masculine.
Got it, thanks.
If you know the gender of the kid, though, IRL you might rather refer to them as "sie" or "er", depending. The "es" here is purely grammatical. :/
Why is the moon masculine? To me is femenine rather than masculine
Just wait until you find out that "the girl" is referred to as "es" as well <.< S.S
I typed kinder, how is that wrong?
Kinder is plural (children),
What's the difference between er and es? When should I use each of them?
When its neuter, es. When you know the gender is masculine, er.
Es is it, Er is he.
Would the use of "das" instead of "es" sound wrong for a german speaker?
Why is Das lernt not correct? Can't you use the definite article to refer to the nominative noun in the previous sentence?
You need a pronoun (replaces a noun, like "it" for "the child"), not an article (accompanies the noun, like"the") here. "Das" can't be used alone, it can't replace Kind.
Why lernt and not lernst?
@ArvindhMani: simply because lernst goes for the second person of singular and 'das Kind' and 'es' is the third of singular
