Plural of gringo; a term used primarily in Spanish-speaking countries to refer to a foreigner, especially a person from the United States.
Possibly from Spanish 'griego' (Greek) referring to incomprehensible speech, or from English 'green' (inexperienced), the exact origin is debated; the term entered English from Spanish American usage.
The word 'gringo' is fascinating because linguists still debate its origin—some think it comes from 'Green-go' (inexperienced travelers), others from 'griego' (Greek, meaning 'unintelligible')—showing how even word origins can be genuinely mysterious.
