You is the second-person pronoun that can be used singularly or plurally. It is the only word in the English language that can be either plural or singular, although it always takes a plural verb form (you are, for example). The distinction between you and ye began to break down by the middle of the 16th century. Ye continued in polite, if informal, use well into the 18th century before it lost respectability. Special plural forms were later contrived to hold you chiefly to singular use, including you-all, you-uns, yez, and youse, but none of them became standard.
Some people write u instead of your and you’re for no particular reason, except perhaps as shorthand or speed writing. In such cases, it isn’t incorrect, but it comes close to being coded jargon that only other people who know the person you’re talking to will understand.
Using You Correctly
The most important thing about you is knowing when to use it and how to capitalize it. When you’re referring to one specific person, you should be capitalized (You are). When you’re referring to more than one person, you should be lowercase (you’re).
Using the Articles
The articles a and an should be used before singular countable nouns that are nonspecific or generic. For instance, a car is more expensive than an airplane, so ‘a’ is the appropriate choice. An is also used when referring to something that has not been specified, such as an elephant or a country.
The band the Who released the single “Who Are You” in 1978. It was their last release before Keith Moon’s death in September of that year. The song peaked at number 7 on the Canadian charts and at number 14 on the US Billboard Hot 100. It remains one of their most popular songs to this day, and is often featured in Who tribute concerts. The track was written by Pete Townshend and played on piano by Rod Argent. The song was a double-A side with John Entwistle’s composition “Had Enough.” Both songs are included on several Who compilation albums. The album cover features Keith Moon wearing an outfit similar to his stage outfit in the late 1970s.
