Relating to Guinea or its people, culture, or language; of or from the West African country of Guinea.
From Guinea (region named from Portuguese Guiné, possibly from Berber aginaw meaning 'black') + -an (suffix forming adjectives and demonyms). The suffix -an is used to create adjectives from place names.
Guinea's name might come from a Berber word meaning 'black,' referring to the people of the region, which shows how European traders named African places based on observations that were sometimes superficial but stuck in history.
