What is an important feature of formal language?

An important feature of formal language is the increased level of vocabulary. Formal language typically involves a more sophisticated and precise use of words, reflecting a higher level of education or professionalism. This type of language is often employed in academic or official settings, where clarity and adherence to standard grammar rules are prioritized. By using advanced vocabulary, speakers and writers can convey their thoughts with greater nuance and formality, establishing a tone that is appropriate for serious discussions, reports, presentations, and other formal communications.
