Final answer:
The correct term for someone who speaks English and two other languages is 'multilingual'. 'Bilingual' refers to speaking two languages, while a 'polyglot' might be proficient in several. These language skills offer academic and professional advantages as seen in educational and occupational settings.
Step-by-step explanation:
The adjective for someone who speaks English and two other languages would be multilingual. This term applies to people who are adept in multiple languages, not just two (which would be bilingual) or one (which would be monolingual). A polyglot is another term that could be used, often implying a proficiency in many languages and sometimes used to describe someone with an interest or flair for languages generally. Multilingual individuals, like college students and professional employees, often find greater opportunities in today's diverse and interconnected world. For instance, bilingual education contributes significantly to academic and professional success, as evidenced by Lucy Alvarez, a college student fluent in English and Spanish whose bilingualism assists her in studying law enforcement.
