If it be found impraticable to print works with the diacritical signs (ˆ,˘), the letter h may be substituted for the sign (ˆ), and the sign (˘), may be altogether omitted ; but at the beginning of works so printed there should be this note: “NB: ch = ĉ; gh = ĝ; hh = ĥ; jh = ĵ; sh = ŝ.”
When it is necessary to make use of the “internal” sign ( , ), care should be taken that it can not be mistaken for a comma. Instead of ( , ), may be printed ( ' ) or ( - ), e.g., sign,et,o, sign'et'o, or sign-et-o.

3. Adjectives are formed by adding a to the root. The numbers and cases are the same as in substantives. The comparative degree is formed by prefixing pli
