One of my foreign friends was teasing me about how English doesn't have a word for "a group of people" whereas many other major languages apparently do, and I replied "sure we do, it's y'all".
I think you mean 'for addressing a group of people'. We have plenty of words for groups of people. And we have ways of addressing them, they just take more than one word: "you -foo-". It's like the infinitive in English is two words, (to -foo-) but in most other euro languages it's only one.
