What characterizes something that is "turgid"?

The term "turgid" typically describes writing or speech that is excessively ornate, overblown, or grandiloquent. When something is characterized as turgid, it often means that the style is pompous or convoluted, laden with overly complex vocabulary or elaborate sentences that may obscure meaning rather than enhance it. This aligns with the idea of being "ostentatiously lofty in style," as it suggests a deliberate attempt to impress or elevate the subject matter, often at the expense of clarity.

In contrast, the other choices describe styles that are straightforward, casual, or direct. These characteristics focus on simplicity and clarity in communication, which runs counter to the essence of turgidity in expression. Thus, the correct answer captures the essence of turgidity as a characteristic of writing that is florid and unnecessarily complicated.
