Ampersand

The ampersand (&amp;), also referred to as the and sign, is a logogram (a diagram standing for a word).
It represents the Latin conjunction "et", which means "and". The ampersand symbol is not only a logogram, but also a ligature. It joins the old handwritten Latin letters "e" and "t" of the word "et", so that the word is represented as a single glyph.
With a c added on it means "et cetera", "and so on".
In everyday writing, the ampersand is sometimes written like a reversed 3 with a vertical line through it.
