At the beginning of each lesson, there is an introduction, but it is only available on PC's. Click on the lesson circle, then click on the light bulb icon. Memrise.com has a short Hebrew alphabet course for Duolingo. You can also google "learn Hebrew alphabet". There are a number of resources on line. YouTube has some things as well. Amazon.com has some books for learning the Hebrew alphabet, too.
Can anyone tell me how in the world I am supposed to be able to read Hebrew instantly?! This app seems like nonsense, especially when Im asked to even write in Hebrew. How??
Benton.1 said that Hebrew has only four conjugations, and that’s true for the present tense. There are masculine singular, masculine plural, feminine singular, and feminine plural. That confused me until I realized that for example ba בא means I come for a male or he comes or it comes if the noun is masculine.
I think you mean את and אתה not אח and אחה (though both of these are also Hebrew words). Notice the difference between chet ח and tav ת. It's good to read all the comments first. You might have found the answer to your question in others' comments. Both mean "you". את/aht is feminine and אתה/ahtah is masculine.
האם אתה בא and את באה do they mean the same thing and why does everything keep changing?
Haim ata ba? האם אתה בא? means “Are you coming?” when speaking to a male.
Haim is a marker for a yes or no question. You usually don’t ever hear this word in casual conversation. So don’t use it; just know how to recognize it.
Ata is you singular masculine, so it refers to a boy or man.
Ba means come and it’s used for a boy coming or a man coming.
At ba’a means You come or Are you coming? to a female depending on the intonation.
You have to read the tips section which is usually available before each lesson.
Or google for example duolingo Hebrew food vocab https://duolingo.fandom.com/wiki/Hebrew_Skill:Food_1
and choose the option with fandom in the title, and all the vocabulary is provided, along with the English translations and sometimes even transliterations! But be careful because some of the transliterations have errors. Check everything with the more reliable Pealim.com.
If you only get the Hebrew, use this site with pealim.com to learn the pronunciation.
