It's difficult to determine the "most communicative" language in the world because there are many factors that can influence communication, including the number of speakers, the diversity of dialects, the availability of resources for communication (such as the internet), and the cultural context in which the language is used.
However, some of the most widely spoken languages in the world include Mandarin Chinese, Spanish, English, Hindi, Arabic, Bengali, Portuguese, Russian, Japanese, and Punjabi, among others. These languages are spoken by millions of people around the world and are used for communication in a wide variety of contexts.
It's also worth noting that there are many different types of communication, including verbal and non-verbal communication, and different languages may be more effective for different types of communication. Ultimately, the most effective language for communication depends on the specific context and the needs of the individuals involved.
