Which term implies overinflation, both physically and metaphorically?

The term that means overinflation, both physically and metaphorically, is "turgid." In a physical sense, "turgid" describes something that is swollen or inflated, often used in reference to plants when they are filled with water to the point of firmness. However, it also has a metaphorical application, particularly in literature and speech, where it denotes a style that is excessively ornate or pompous. This dual meaning captures the idea of being inflated in both a literal and abstract way, making "turgid" the most fitting choice for the question posed.

Other terms, while having their own meanings, do not convey this idea of inflation. "Propitiate" relates to appeasing a god or spirit, "vitiate" refers to impairing or damaging something, and "wend" means to follow a course or go in a direction. None of these capture the concept of overinflation in the same way that "turgid" does.
