It has several meanings: 1. Equivalent of english questions endung with isn't or aren't or haven't you? etc. Example: Ты ведь помыл посуду? You washed the dish, didn't you? 2. Showing reason or supportive arguement. Example: Он ничего не сможет сделать, ведь он трус. - He won't be able to do anything, because he's a cơard. Не ходи туда, ведь там так страшно. - Don't go there. It's so spooky there. 3. Adding more meaning or emotion. (Equivalent of "же"). Examples: Зачем ты с ним дружишь, он ведь (же) такой глупый! How come you're friends? He's so stupid! Those are the main meanings I can think of at the moment. 😅

Это слово служит для усиления выразительности./ This word serves to enhance expressiveness. Прим./Example: А ведь я вам говорил это давно.

David, as common as "nevertheless" or "after all". You must know this word, but you shouldn't use it everytime. As Dmitry noted, the most common word to express this idea is "же"... which is really important to know but is harder to explain:) Do you know a Sanscrit word "veda", "knowlge" (as in Vedas)? You must know. Russian has a verb "ведать", to know, it is a cognate. "Видеть", to see, is related. English "wit", "wise" "wizard", also "guide" (via french). Ведь is formed from it, and originally it meant "I know". It means something like "for I (we) know that...", "after all, ...". As a conjunction it can be substituted with потому что "because". The difference is that "because" is bare logic. A -> B. It is about how facts relate to each other. "Ведь" is about what we know, what seems to us, what is obvious, what suggests what. It is placed before a statement of an obvious or known to us fact. It comes after something that seems to be suggested by this fact. I means that the former seems to obviously follow form the latter. You must know the word "wit", [ведь] you [же or ведь] are British. Here you can use "ведь" or "же" or both.

"Ведь знал же я, но не пошел" 6) В вопросительных и восклицательных предложениях означает "неужели не?", "разве не?" //In interrogative and exclamation sentences means "неужели не?", "разве не?" Ведь ты исполнишь свое обещание? правда? 7) То же с отрицанием в значении "неужели?", "разве?" //Also with the negation of the value"неужели?", "разве?" Ведь не ребенок же я, сам понимаю.

It is used to assure in something. It can express a doubt as well. Enough to change intonation: "... Ведь you are British, eh?" "I hope he does. Ведь he is British." Sometimes the implication is not stated. For example: A: "I'm going to attend his performance in Kinshasa tomorrow". B: "Но это ведь в Африке!!!!" "Ведь" refers to the implication: it is not really easy to get to there. In a question: Ты ведь англичанин? Here I'm asking to confirm this and imply that I've relied or that I'm going to rely on some implication of this fact.
