latex: fonts terminology

here i will try to describe some confusing terms i’ve used while setting up my latex document:

font sizes

in latex font size is declared by using special commands:

i also want to note that these commands are relative to the size set in document’s preamble

styles in latex are bold, italics, underlined, etc.

a font family, or typeface, is a collection of characters that belong to one of the following groups:

for example, (1) times new roman is considered a serif font, (2) arial - sans-serif, and (3) courier - monospaced.

to stay consistent in configuring font settings i prefer the following workflow order:

family → style → size

i’ll explain what tex commands i use in another note later. see note #62.
