Here's why:
* Context: Formal language is often associated with situations demanding a certain level of formality and respect. Writing often takes place in more formal contexts:
* Academic papers: Research papers, essays, and dissertations require a high degree of precision and objectivity.
* Business communication: Formal emails, reports, and proposals demand clear, professional language.
* Legal documents: Contracts, wills, and other legal documents must be unambiguous and precise.
* Audience: Writers often tailor their language to a specific audience. In formal writing, the audience may be unfamiliar or require a more professional tone.
* Time for Revision: Writers have more time to carefully craft their language and ensure it's grammatically correct and stylistically appropriate.
While formal language is occasionally used in spoken English (like speeches, presentations, or formal debates), everyday conversation usually favors a more casual and informal style.
In summary, while formal English has its place in speech, it's much more common and necessary in written communication.
