Would you distinguish between pretentiousness and preciosity? I associate pretentiousness with non-fiction - using words like "centering" or "instantiation" - and preciosity with florid fiction. I asked my pal ChatGPT for an example of precieux prose, and here's what he/she/they/it came up with, including the explanatory final paragraph:

"In the ethereal realm of the garden, where delicate zephyrs dance among resplendent petals, one might chance upon the dainty damsel, her countenance akin to a radiant blossom caressed by the morning dew. Her melodious laughter, a symphony of tinkling silver bells, reverberates through the fragrant air, ensnaring the hearts of onlookers in a web of enchantment. She, the ephemeral embodiment of grace and charm, adorns her gown with intricate lace, every stitch an ode to the celestial artistry that weaves the tapestry of existence."

Critics may label this passage as "précieux" due to its extravagant language, elaborate descriptions, and an almost exaggerated focus on aesthetics. The use of poetic devices, such as metaphors and personification, further contributes to the overall effect.
