Hello, Friends - Today's letter is H. From the Formal "How do You Do?" to the informal "Howdy," the casual "Hello" to the even more casual "Hi," we greet people with H on a regular basis in English. But it isn't just English. Many languages greet people with an H. So, whether you say Hello or Hola, Hallo or Hei, Halla, Halo, Hej, Hujambo, or just plain Howdy, it's good to see you here today. Good to have a chance to say Hi. How do you say Hello?
