Indo- European Languages
Indo- Iranian Branch
In the branch of Indo- Eurpoean, the most widely used language is Indo- Iranian. Hindi is spoken in many different ways- and therefore could be regarded as a collection of many individual languages.
Romance languages evolved from Latin spoken by the Romans 2000 years ago. As the conquering Roman armies occupied the provinces of their vast empire, they brought the Latin language with them.
