## Translingual
### Description

An S-shape with one or, in some typefaces, two vertical lines crossing it completely. See for the usage with explicitly two lines.

### Etymology

$ appears to have evolved circa 1775 in the United States from a common abbreviation for pesos, also known as piastres or pieces of eight, a P/raised-S ligature P$^S$. It was used in the US before the adoption of the dollar in 1785.
The "computing" sense is the result of homophony between English cache and cash, dollars being a form of cash.

#### Usage notes

When used as a currency symbol, $ precedes the number it qualifies in English, despite being pronounced second. For example, "$1" is read as one dollar, not dollar one unlike the usage in languages such as French or German: "1 $", "2,50 $".
When used for the Portuguese escudo, $ is placed between the escudos and centavos, e.g. 2$50. The official symbol for the escudo is (with two bars), but that form is unified with the single-bar form in Unicode. A single-bar dollar sign is frequently employed in its place even for official purposes.
