It is not like a French r and it is not usually trilled. I am a native speaker and have a trilled r and it is considered quite odd. Not odd enough that people think I have an accent, but odd enough that people might comment. Frankly if you go French or trilled you'll probably be fine.
Thanks. Just a grey point still left for me. I've learned other semitic language (Arabic) before. In there, pronouns (like هذا which equals to זה , I guess) are treated as always known nouns. So there is nothing like الهذا (the = ال). Isn't this rule true in hebrew as semitic language? Also the phrase, "This book" ( = هذا الكتاب in Arabic) isn't considered a complete sentence. Is it true for "זח הספר" or "הזה הספר" in hebrew too?
Thanks in advance.
No, this rule doesn't apply for Hebrew. ה הידיעה (the modifier hé) is coming before the modidied noun AND the adjectives. If you want to say 'a good book' you say "ספר טוב" (sefer tov), but if you want to say 'THE good book' you modify both good and book - "הספר הטוב" (HAsefer HAtov). Now, regarding זה. It can mean several things. It is a book - זה ספר (you studied araboc so I feel obligated to tell you that it's also possible to say זהו ספר (zehu is a short for זה הוא) It is the book - זה הספר (also possible זהו הספר) This book - ספר זה or הספר הזה HTH :)
Ruqiyah, the "Discussion" is meant for students to ask questions about things they don't understand about the Hebrew sentence. It's not to be used as an exercise book to rewrite the sentences, make self serving comments, or juvenile jokes. I've noticed in the last couple of days that you seem to rewrite every sentence you do. When people start to do this, it just clogs the discussion forums with spam and it gets hard for people to find the answers to question they have asked. Duolingo Spanish and Italian have gotten so bad that some of the discussion have more than 300 comments, most of them spam, so that students have a very hard time trying to find the help they need. You can go back and delete any of the comments that you do not want seen on the discussion forms. I will delete this comment once I feel you have seen it. Good luck with your Hebrew studies. I see you are already at level 9.
Up Date: I forgot to mention that you are filling up a lot of people's mailboxes with spam too. Because, every time you make a comment on any of the discussion forums, an e-mail goes out to everyone who has made a comment on any of the discussions, or is following any of the threads, to which you are adding a comment. So, each time you make a comment, all of us get an e-mail telling us what you said. That's a lot of e-mail going out to a lot of people.
