Talking of Strategy& and the use of ampersands as we were below, the ampersand today is used primarily in business names — Johnson & Johnson, Barnes & Noble, Dolce & Gabbana, etc.
The elegant symbol in fact dates from the days when Roman scribes wrote the Latin word et, which means “and”, with a ligature to blend the two letters into a single letter form.
The actual word “ampersand” came into being many years later. The “&” had become such a standard part of the English alphabet over the centuries that by the early 1800s school children reciting their ABCs concluded the alphabet with the “&”, the 27th letter.
As it would have been confusing to say just “X, Y, Z, and”, students said: “X, Y, Z and, per se, and.” “Per se” means “by itself,” so the students were essentially saying, “X, Y, Z, and, by itself, and.” Over time the “and per se and” was slurred together into the word we use today: ampersand.
