Interlingua is an international auxiliary language that uses simple grammar and vocabulary common among Romance and Germanic languages. This means that it is a great option for speakers of those languages looking to learn another, or for speakers of other languages who are looking for a nice gateway in English, Italian, Spanish, French, German, etc.
