What does grammar govern in a language?

Grammar serves as the framework of a language, establishing the rules and structures that enable effective communication. It governs how words are combined to form sentences, dictating the correct use of syntax, punctuation, and other elements that contribute to clarity and cohesion in spoken and written language. By adhering to grammatical rules, speakers can ensure mutual understanding, allowing both the speaker and the listener to interpret the message accurately. This mutual understanding is essential for effective communication, as it reduces ambiguity and promotes clarity in conveying thoughts and ideas.

Other options such as spelling, cultural differences, and pronunciation are aspects of language but do not encompass the broader role that grammar plays in facilitating clear and effective communication among speakers. While these elements are important in their own right, they do not govern the structure and usage that support shared understanding in language.
