The term "Indo-Germanic" is often used to describe a branch of the language family that includes languages such as English, German, and Hindi. However, this term is considered outdated by many linguists and has been replaced by more accurate and inclusive synonyms. One commonly used synonym is "Indo-European," which is a broader term that includes languages such as Greek, Latin, and Slavic. Another synonym is "Indo-Aryan," which specifically refers to the branch of Indo-European languages that includes Hindi and other languages spoken in India. Other possible synonyms include "Indo-Iranian" and "Aryan." While each of these terms has its own history and connotations, they are all more accurate and inclusive than the outdated term "Indo-Germanic".
