Which term describes a style that is overblown and extravagant in nature?

The term "grandiloquent" refers to a style that is characterized by grandiosity, extravagance, and often an overly elaborate or pompous manner of expression. It conveys a sense of being theatrical or excessively ornate, whether in speech, writing, or artistic presentation. This aligns perfectly with the idea of being overblown, as grandiloquent styles often aim to impress or astonish, sometimes at the expense of clarity or simplicity.

In contrast, the other options represent styles that are fundamentally different from what is described. "Minimalist" emphasizes simplicity and reduction, "subdued" implies a restrained or moderate approach, and "reserved" denotes a sense of restraint or self-control, all of which stand in stark contrast to the extravagance associated with grandiloquence. Thus, grandiloquent most accurately captures the essence of being overblown and extravagant.
