Hallo, hier sind ein paar einfache Wörter, die du kennen solltest, wenn du ein A1-Deutschsprecher bist [Translation: Hello, here are a few simple words you should know if you are an A1 German speaker]

Hallo = Hello. by far the easiest and most beginner phrases.

Guten Tag = Good Day, also rather simple, one of the first words you learn in German alongside Hallo and a few others.

Guten Morgen = Good Morning, commonly seen alongside Guten Tag, although more common than Guten Tag.

Gute Nacht = Good Night, the reason this word doesn't have the n of Guten but still has the e stopping it from being just Gut, this is because Nacht is feminine, so Gute is the feminine modified version, because Nacht is feminine, it becomes Gute

Tschüss = Goodbye/Bye. simple enough

Bitte = Please. also simple

Ja = Yes

Nein = No

Danke = Thanks/Thank You.

etc.
