meta
/me't*/ or /may't*/ or (Commonwealth) /mee't*/ A
prefix meaning one level of description higher. If X is some
concept then meta-X is data about or processes operating on
X.
For example, a {metasyntax} is {syntax} for specifying syntax,
{metalanguage} is a language used to discuss language,
{meta-data} is data about data, and {meta-reasoning} is
reasoning about reasoning.
This is difficult to explain briefly, but much hacker humour
turns on deliberate confusion between meta-levels.
