In order to avoid uncertainty regarding the words to be sub- stituted, the last word that according to the above rule could be placed in front of the opening bracket is, wherever possible, placed inside the bracket and repeated for each alternative. 3.9 Use of terms printed in italic type

The basic forms of all terms printed in italic typeface are listed in the index at the end of the part (see 3.11). An asterisk is used to separate terms printed in italic typeface
