I assume you meant all meals. Yes, "das Essen = the food, the meal".
some extra info:
- das Frühstück = the breakfast
compound nouns have the same gender as the last noun so since "Essen" is a neuter ("das") noun we also have:
- das Mittagessen = the lunch
- das Abendessen = the dinner (meaning evening meal)
You might have noticed all three of the major meals are neuter gender (das) :)
Yes, because "esse" would essentially be used as a verb and then as a noun. Essen has different meanings depending upon how it is being used in a sentence: https://www.duolingo.com/comment/908359 . Please note there are derived words from the base "Essen" form such as Abendessen (for dinner).
Ich esse das Abendessen (I eat the dinner)
Well, most words in any language are going to have multiple appropriate translations. Translations should not be considered one-to-one, especially with single words.
You have to learn the concept of the word in the native language more so than the literal translation. You want to express a similar "idea", but not necessarily similar words or phrasing. In other words, you're not just translating the word "delicious"; you're translating the "idea" of something tasting good.
The best way to learn the meaning of words and how to use them is to read a lot in German or listen/speak to native speakers.
But if you're really new to German, and still not able to understand words in context, I recommend just learning the simple translations for now. Worry about perfect translations later.
So yeah, in short, just go for whatever seems like the best translation to you.
