What is the term for language that is overly wordy or inflated?

The term that accurately describes language that is overly wordy or inflated is "verbiage." This word refers to an excessive use of words in speech or writing, often leading to a lack of clarity or conciseness. Using verbiage can make communication less effective, as it may obfuscate the intended message. In contrast, the other terms do not relate to the concept of using excessive language. "Vilify" refers to speaking about someone in a harshly critical or slanderous manner. "Viscous" is a term used in science to describe a thick, sticky consistency, often in relation to liquids. "Xerography" is a process used in photocopying and printing. Therefore, "verbiage" is the most suitable term for describing inflated language.
