• Often confused with e.g.: In correct use, i.e. is used to explain, clarify or rephrase a statement, whereas e.g. is used to list examples.
  The correct use of i.e. differs from that of viz. in that what follows i.e. merely restates in other words what has already been said, whereas what follows viz. expands upon what has already been said; and it differs from the correct use of e.g. in that completeness or near-completeness is suggested by i.e., whereas e.g. introduces a not complete and often only small selection of examples.
• American English prefers a comma after i.e., but British English usually does not use a comma there and often does not use dots either.
• Opinion is mixed about whether the abbreviation should be italicized, or whether there should be a separating non-breaking space as in i. e., or whether this matters at all. However, the AMA manual of style recommends to forgo italic on terms long since naturalized into English and not to separate abbreviations (see "Abbreviation" on Wikipedia).
