Is there no Latin word for Tea? Upon my soul, if I had known that I would have let the vulgar stuff alone.

The remark plays on Belloc’s persona as a combative classicist and cultural traditionalist. The joke hinges on the idea that a thing’s dignity depends on whether it can be named in Latin—the language of the Church, scholarship, and “civilized” inheritance. Discovering that “tea” lacks a classical Latin term (it entered Europe much later) prompts mock-disgust: if it cannot be naturalized into the old learned vocabulary, it must be “vulgar.” The line satirizes snobbery and pedantry even as it indulges them, revealing how linguistic prestige can be used to police taste and social belonging.
