Introducing Yourself and Other

Maybe....
 you just stand there and don't really know how to begin when you want to introduce yourself or someone else to an English native speaker. Your intention, however, was to leave a lasting first impression at the beginning of a conversation. The following phrases will help you to introduce yourself both casually and confidently. If someone is introduced to you, you may reply "Nice to meet you" and introduce yourself afterwards

Introducing yourself is much more than saying your name; it’s a way to connect with someone new by exchanging words and often, physical contact. Introducing yourself to strangers can be tricky because what you say depends entirely on the context. You may introduce yourself differently depending on whether you are addressing an audience before you give a speech, meeting someone at a networking event, or just starting a conversation with a new person at a party. What is important is to introduce yourself in a way that is appropriate and makes people like and remember you.

Introducing Yourself

“Hello, my name is...”, “Hi, I’m....”, “Hello (your name)” “Good afternoon. May I introduce myself? My name is... (formal)

Introducing Other People to Someone

If you want to introduce an acquaintance, a friend, a relative or a colleague to someon, you may do so by using the following phrases.

“ I’d like you to meet my friend/colleague/brother..”, “This is my friend”, “May I introduce... to you? (formal)”, “Have you met...?” “This is”
