What term describes language that is swollen or overly ornate?

The term that describes language that is swollen or overly ornate is "turgid." This word is often used to characterize writing or speech that is excessively complicated or embellished, making it difficult to read or understand. Turgid language typically includes elaborate phrasing, unnecessary adjectives, and unnecessary complexity that can obscure the intended meaning.

In contrast, while "verbose" refers to using more words than necessary to convey an idea, and "prolix" suggests excessive length in speech or writing, neither captures the specific connotation of being swollen or ornate as well as "turgid." "Bombastic," while also related to grandiose language, has a connotation of ostentation intended to impress others rather than just to be excessively ornate. Thus, "turgid" is the most precise term to denote language that is both overly inflated and ornate.
