What is a group of Purists called?

A group of purists is commonly called an Obstinacy.

Collective nouns can be intriguing for grammar purists. These nouns are distinct from other nouns, as they highlight a group of individuals or things in a singular form. Rather than referring to each member separately, collective nouns bring together entities as a unified whole. These noun phrases possess a certain charm, effortlessly capturing the unity and harmony that exists within a group. Examples of collective nouns offer a glimpse into the symphony of language. When one ponders a "fleet" of ships, it conveys the idea of multiple vessels moving together purposefully. Similarly, a "flock" of birds portrays a delicate choreography as they soar through the sky in perfect unison. Envisaging a "bouquet" of flowers brings to mind a harmonious arrangement, each bloom complementing the others to create a stunning display. Notably, collective nouns can reflect the distinctive identities of certain groups. A "pack" of wolves embodies the canine family's relentless teamwork and survival, while a "pride" of lions represents their noble and regal kinship within its hierarchy. These collective nouns encapsulate vivid imagery and evoke deeper emotions, offering a poetic perspective that celebrates the unity or shared purpose within these groups. While some claim collective nouns do not strictly conform to grammatical rules, purists find beauty in their uniqueness. These nouns challenge conventional structures, prompting us to appreciate language's adaptability and capacity to evolve. Grammar enthusiasts revel in the pages of history, where collective nouns have weaved themselves into our communication, adding depth and character to literary works, speeches, and conversations alike. For the grammatically passionate, collective nouns are a worthy fascination. They bestow life upon our words, enabling us to convey the essence of unity and togetherness succinctly. As language develops toward ever-intricate pathways, collective nouns remind us that, at times, a seemingly singular entity requires a nuanced touch.
