In general all the three persons oft the singular habe different forms of conjugation. You have to get used to it ;-)
For the plural forms it is easier: first and third Person are always like the infintive form, except the verb "sein". And the second person in plural is often similar to the third person singular.
In the case oft the verb " essen" it is a bit special, the second and third person singular are similar.
ich esse, du isst, er isst, wir essen, ihr esst, sie essen.
Not quite, but you're getting the right idea that one verb has different forms depending on if it matches with "you" or "I" or "he" or "they", etc. These forms are called conjugations, and they are formed by conjugating the verb (choosing the right ending to put on it).
Ich esse = "I eat"
Er isst = "He eats"
Note that English also conjugates the verb (compare eat with eats), although where English recycles the same form in multiple situations (also "they eat"), German has more versions (sie essen).
Duolingo's lesson tips show the conjugation of essen if you scroll down. You can also look up the full conjugation of any verb on Verbix or Canoo.net. Those sites have a lot of extra information you don't need yet, so just focus on the 'Present Indicative' section.
I have a question when you go to germany or talk how will the german or who are talking in german are going to get what im saying for example [Er ist]=means he is eating How are they going to know what im saying really saying because they can thi k that i said he is
Pls help Danke. :)
I ate an apple [...] why eat:
The German "ich esse" is present tense, so the English translation must be present as well, therefore it's "I eat", not "I ate" (which would be "ich aß" in German).
or a apple
"a apple" is wrong in English, it must be "an apple". "an" is used instead of "a", when the following word begins with a vowel sound (as apple does)
why not ich bin esse einen Apfel
You try to form a progressive present in German, which does not exist. There are no progressive tenses in German. Both "I am eating" and "I eat" translate to "ich esse".
By the way, the first two questions have already been answered - so next time please first read the other comments.
ein Apfel is the nominative case, einen Apfel the accusative case.
The subject of a verb is in the nominative case -- so you would use ein Apfel when the apple is the one doing or being something.
The direct object of a verb is in the accusative case -- so you would use einen Apfel when the apple is having something done to it.
For example: Ein Apfel liegt auf dem Tisch. Ich sehe einen Apfel auf dem Tisch. "An apple lies on the table. I see an apple on the table."
In the first sentence, the apple is the one that is doing the lying on the table; in the second one, the apple is the one that gets seen by me.
The accusative case is also used after certain prepositions.
I ts not right
