rubric
noun
[ ˈruːbrɪk ]
• a heading on a document.
• a set of instructions or rules.
Origin:
late Middle English rubrish (originally referring to a heading, section of text, etc. written in red for distinctiveness), from Old French rubriche, from Latin rubrica (terra) ‘red (earth or ochre as writing material)’, from the base of rubeus ‘red’; the later spelling is influenced by the Latin form.
