**encoding**- This specifies the order that characters appear in the
font. The two most common text encodings used in L
^{A}TEX are Knuth's `TEX text' encoding, and the `TEX text extended' encoding developed by the TEX Users Group members during a TEX Conference at Cork in 1990 (hence its informal name `Cork encoding'). **family**- The name for a collection of fonts, usually grouped under a common name by the font foundry. For example, `Adobe Times', `ITC Garamond', and Knuth's `Computer Modern Roman' are all font families.
**series**- How heavy or expanded a font is. For example, `medium weight', `narrow' and `bold extended' are all series.
**shape**- The form of the letters within a font family. For example, `italic', `oblique' and `upright' (sometimes called `roman') are all font shapes.
**size**- The design size of the font, for example `10pt'.
