Resembling or characteristic of baragouin; unintelligible, garbled, or incomprehensibly spoken.
From baragouin + -ish suffix (resembling or somewhat). A derivative adjective form from the 18th-19th century for describing confusing speech.
Adding -ish to baragouin shows how English creates descriptive adjectives—'-ish' originally meant 'somewhat' and still does, so baragouinish meant 'somewhat like gibberish,' perfectly capturing partial incomprehension.
