Page "Gibberish" Paragraph 1

One etymology asserts it is derived from the root of the Irish word gob or gab ( mouth ), which the same source asserts is the root of jabber, gibber and gobble.

The word may derive from the word " jabber " (" to talk nonsense "), with the "- ish " suffix to signify a language ; alternatively, the term gibberish may derive from the eclectic mix of English, Spanish, Hebrew, Hindi and Arabic spoken in the British territory of Gibraltar ( from Arabic Gabal-Tariq, meaning Mountain of Tariq ), which is unintelligible to non-natives.
