In my post about headlines a few days ago, I called them "heads." This isn't the preferred newspaper spelling. The green-eyeshade folk use "heds."
Likewise, the beginning of a story isn't the "lead." It's a "lede." I've heard this was to avoid confusion between lead type and reporters' work, back in the days when dinosaurs roamed the planet.
"Paragraph"? Nope. Try "graf."
Now that I've gone to the trouble of mentioning these all, I'll also tell you that I don't like them. They're fine in a newsroom context. But in this blog I stick to readable, comprehensible names. (When I don't forget myself.)
