"Cross-linguistic" refers to the comparison and analysis of languages beyond one's own native language. Synonyms for this term would include "multilingual," "interlinguistic," "translingual," "bilingual," and "cross-cultural." These terms indicate an understanding that language and culture are interdependent and that a broad perspective is needed for effective communication and studies across multiple languages. In our globalized world, cross-linguistic research is becoming increasingly important in fields such as linguistics, education, and international business. By recognizing synonyms for "cross-linguistic," we can broaden our language and cultural perspectives, which can ultimately lead to better communication, understanding, and cooperation across borders.
