Tháinig sé sna gháth chaint ó lucht ríomhaireachta:
http://dictionary.reference.com/search?q=meta quote:
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.
