Steph, if ever you try online dating, "beautiful majestic semicolon" has to appear in your profile somewhere.
Yes, because I'm not celibate ENOUGH....
Cindy, a "nut graf" is, in a news article (generally), the paragraph that contains the gist of the news story. It's usually -- or, rather, in a well-written article, it SHOULD be -- very close to the beginning of the article, often the 2nd or 3rd paragraph. Though, by the same token, it's generally not the first paragraph, which is often descriptive or anecdotal, to hook the reader.
Here's an example I pulled from WDSU.com:
Katrina Weakens Further; Storm Now Category 1
NEW ORLEANS -- The Big Easy is breathing a bit easier right now.
Hurricane Katrina has spared New Orleans a direct hit, but its effects are still being felt there and elsewhere along the Gulf Coast.
Less than one hour after downgrading the storm to Category 2, forecasters lowered their assessment of the hurricane to a Category 1 storm with winds of nearly 95 mph. Officials said they expect the storm to get weaker Monday as it moves over land, but widespread damage is being reported on the southern coast of neighboring Mississippi.
The nut graf is actually the 3rd paragraph there. Specifically, the sentence in blue -- it's the gist of the article, what the story is really trying to convey.
