why we use silent characters before Knife, know etc.? In short why we use silent characters in english.?

They are relics from the language the word was adapted from.  English has traces of latin, Greek, French, German, Saxon, and Old Norse, and words with similar silent letters were from the same mother tongues.  Hence, walk, talk, and stalk are related; reign, malign, sign, and feign are related; and knob, knock, knoll, and knee are related.  The distinctions aren't entirely clear, because there's a lot of interbreeding among languages, and the people who codified english spelling weren't exactly linguistic scientists.

Rather than Morse code (which, as you say, is the letter U), I think it might come from WRITING something and finishing it with :- (or maybe two periods, points or full-stops and a dash - maybe a slanting one) to indicate "That's the end of it - no more discussion!"

Would it help to encode the characters before storing them, and decode the characters when reading them? That way you can easily mix character sets.\n\nRawlyn.

I was taught a simple way to know which is correct.  Say the sentence without the other person's name. As in: "Me & Kathy went to the store" becomes: "Me went to the store." Obviously "Me" is incorrect.  Another: "It was a secret known only by me & Kathy". Becomes: "It was a secret known only to me". In this case "me" is correct.\nThis works every time!

Most likely stealth. Make sure all the letters are in the correct spaces. :)

RELAXATION  that's the only word I could find on www.magswordfinder.com and that was using the ? as any letter the computer could find.  Without the ? there were none.

next to the 0(zero key)is the hyphen-   push the hyphen key and shift at the same time.\n\nso instead of -, you will get _.\n\nYAY!

It depends on how you're using them. I would say that most of the time you would NOT want it in the parantheses.\n\nFor example:\nDo you like the show Crime Scene Investigation (CSI)?\nOne of the most popular TV shows is CSI (don't you love that show?).\n\n\nI'm wondering if you meant to ask about punctuation in quotation marks??  If this is the case, the proper use is different between the US and UK/Canada.  In the US, the punctuation always goes inside the quotation marks.  Outside of the US, there are a number of rules around that.  See the link below for more details.

You're referring to the use of ellipses (...) Just so you know, it's typically three periods at a time.\n\nI occasionally use them to highlight an incomplete or trailing thought.  I think they are an effective literary tool, but I wouldn't overuse them or people will think you don't have anything concrete to say.

I've used the International Phonetics Alphabet (IPA) as written code before.  Basically it just gives you one symbol for each sound.  Typically I just use it as shorthand in class when taking notes on peoples' names I can't spell and such... \nAnyway, it's cool if you and a friend know it, you can write notes in it that most people can't read.  I did that when I was younger.

I'm working and studying in Taiwan, where we use traditional Chinese characters. Recognition was a serious problem for me until I started learning how to write the characters. Yes, I still can't see all the strokes, but somehow I can recognize even the most intricate characters far easier after practicing to write them. Guessing from radicals are very dangerous, because the characters with more that 15 strokes often have more than one radical in them (or so it seems to someone learning the language). You could guess totally wrong if you think you see a radical, but it's not really the correct radical but a set of strokes similar to some radicals.\nGood luck! I know it's not so easy, but try the writing bit. It works for me.

I think it's just the using of letters. Just like unknowns are usually called x, y, stuff like that.

I'm sorry I'm replying without answering the question, but please, PLEASE, PLEASEEE never never NEVER put an unnecessary apostrophe in the posessive form of "its." I can see maybe leaving out a necessary apostrophe if you're too lazy, but adding one just demonstrates ignorance, because technically it takes more time to do so. Please don't, for the more sensitive among us. Open a grammar book. It's a tragedy the subject's not taught these days.

I've always thought it didn't make sense. Truth is, a lot of profanities were once perfectly acceptable words. 'C---' was used by Chaucer in the Canterbury Tales, and is the derivation of the word 'quaint' (and rhymes with how the word would have sounded in Middle English). A 'W---' was American military slang for a bed in WW2, and I'm sure you can use your own imagination for how it's meaning changed. Despite what people might tell you, no one really knows the derivation of the word 'F---' but what is known is that it's earliest recorded use is the 13th century.\nAnd so on.\nWhat I find most odd is how people substitute other words for a profanity. For example, someone might say, 'Oh sugar!' instead of a more robust, 'Oh S---!'. This, it seems to me, is daft. In this case everyone knows what the word 'sugar' is replacing and so it has the same meaning. We might say that is fine, but the word 'sugar' is not so ugly. Well, fair enough. That might be the case now but how long will it be until 'sugar' etc are deemed profanities just like our modern swear words were once acceptable.\nI don't mind swearing. There's a place for a good, well-timed, 'Oh F--- off!' And neither do I think it's a limited vocabulary. Those words do the job VERY well at times. What worries me most are the semi-literate idiots who punctuate sentences with, 'you know what I mean', 'yeah' and 'right' etc. I find that far more offensive.

This is a French word and the "s" is silent.\n\nSue

The reason is very simple. Non-native users of the language normally tend to spell by the sound rather than focus on punctuation and/or spelling. And with English being the global language that it has become, native users should be a bit more considerate, taking into consideration that they are in a state of being able to decipher what actually is meant to be conveyed by the non-natives.

Wheee!!! Really looking to stick it to Americans... until we look at your written mechanics. LMAO!!!\n\nNo capital letters, internal comma is missing, hmmmm....\n\nGotta love it!
