What is the difference among "viz.", "i.e.", and ":"? In listing items, I wrote as follows. [1] There are four members in my family: father, mother, sister, and me. [2] There are four members in my family, viz., father, mother, sister, and me. [3] There are four members in my family, i.e., father, mother, sister, and me. First, am I right about the usage of these expressions? Next, are there any difference in nuances among them? Also, could you give me some examples where only one/two of them is/are appropriate if any? Thank you in advance.
