what is did dash say about the work
Answers
Answer:
The dash (—), also called the em dash, is the long horizontal bar, much longer than a hyphen. Few keyboards have a dash, but a word processor can usually produce one in one way or another. If your keyboard can't produce a dash, you will have to resort to a hyphen as a stand-in. In British usage, we use only a single hyphen to represent a dash - like this. American usage, in contrast, uses two consecutive hyphens -- like this (A). Here I must confess that I strongly prefer the American style, since the double hyphen is far more more prominent than a single one and avoids any possibility of ambiguity. If you are writing for publication, you will probably have to use the single hyphen; in other contexts, you should consider using the more vivid double hyphen. In any case, you will be very unlucky if your word processor can't produce a proper dash and save you from worrying about this.
There are two slightly different conventions for using a dash. The more modern one is to put white spaces at both ends of a dash, while the older style uses no white spaces at all, but writes the dash solid next to whatever precedes and follows it. Both conventions are in use, and hence you may see either of the following:
The Serbs want peace — or so they say.
The Serbs want peace—or so they say.
I prefer the first style, since it is much easier on the eye, and I recommend that you adopt this style.
The dash has only one use: a pair of dashes separates a strong interruption from the rest of the sentence. (A strong interruption is one which violently disrupts the flow of the sentence.) Again, note that word `pair': in principle, at least, dashes come in pairs, though sometimes one of them is not written. (Remember that the same thing is true of bracketing commas, which set off weak interruptions.) Here are some examples:
An honest politician — if such a creature exists — would never agree to such a plan.
The destruction of Guernica — and there is no doubt that the destruction was deliberate — horrified the world.
