meta

One definition of this Greek word is transcending, or going above and beyond. In the computer field, it defines things that embrace more than the usual. For example, a metafile contains all types of data. Meta-data describes other data. See metafile, metadata and meta tag.

1.(language)META - The assembly language for the CYBER 200, developed at CDC ca 1977.

[CDC Pub 60256020].
2.(philosophy)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.
