You is a plural form of the singular word you. It triggers plural verb agreement. Historically, you was used only in the dative case. Today, it is used in all cases and all numbers. If you are talking to someone who is not related to you, use you instead. There are several other uses of you. However, you may be mistaken for someone else. It’s always better to use the singular form of you.
First, use a general greeting, such as “how are you?” The phrase has two meanings: an adjective and an adverb. When addressing a person, you can use “good” as an adjective and “I’m doing well” as an adverb. A polite greeting doesn’t include a person’s gender. In a business setting, you can use “how are you?” if you want to greet a person.
Another confusing spelled-out word is homophone. The homophones, which are similar but have different meanings, may be confusing for English online listening learners. To avoid this error, you should avoid using contractions in your documents. If you use the contraction “you’re” in an email or other document, it can cause confusion. Also, spell check may not catch homophone errors. Nevertheless, it’s worth knowing the difference.
Another way to say “what are you doing” is to ask: What are you doing? This question has many meanings and can be used casually. It can mean what you’re doing right now, what you’re planning on doing later today, or what you’ve been doing recently. It also has an unmistakably casual and informal connotation. If you’re wondering how the word “what are you” works, here’s a hint.
