thank u everybody.....

to "say" something means you dont really have to be talking to anyone in particular. It's just speaking. to "tell" something usually will imply you are talking directly to someone for a reason. Almost liek you are giving information. For example: "Tell us your name." - means the person wants you to say your name specifically to them. So when you say it, it's for them. "Say your name." - You aren't talking to anyone in particular, just saying it outloud to anyone. Whoever hears it and remembers it will be the person paying attention. "Ask" is for asking questions. One thing to note, though. Say and Tell can often similar meanings such as. "He told me he would bring food." and "He said he would bring food." The reason this can be used and mean the same thing is because he was only talking to one person anyway, you. "He told us he would bring food." and "He said he would bring food." Ok now he is talking to a group of people. So for "tell" it has to change to "told US" because he was specifically talking to that group of people. Notice how the second sentence stays exactly the same. even though he was talking to a group. It's because when you use "say" you dont have to be talking to anyone in particular. It's long but I hope it makes sense.

"say" and "tell" mean the same, but have different grammar. "ask" = ask a question

If you are giving information = "say" and "tell" If you need information ="ask" Say and tell have a lot of differences. They are explained clearly here: http://www.englishclub.com/vocabulary/cw-say-tell.htm

say and tell are statements ask is a question :P
