9.10 Classification as to form
     9.11  To insert or to add words or a paragraph.
     9.12  To strike out words or a paragraph.
     9.13  To strike out and insert (which applies to words) or to substitute (which applies to one or more paragraphs).

9.20 To Amend by Substitution
     9.21  A motion to amend by striking out one or more paragraphs and adding one or more new paragraphs as a replacement is called a motion to substitute. In the case of a motion to substitute, the pending question is first opened to improvement by secondary amendment; then opportunity is given to amend the proposed substitute--so that both the pending question and the substitute may be put in the most desirable form before the vote is taken on whether the substitution shall be made. If the motion to substitute is carried, the substituted material can no longer be amended except by adding nonmodifying matter.

9.30 Primary and Secondary Amendments
     9.31  A primary amendment amends a main motion. A secondary amendment amends a primary amendment. (It is sometimes called an amendment to the amendment). A secondary amendment cannot be amended since it would make parliamentary procedure too complicated.

9.40 Improper Amendments
     9.41  Improper amendments include those that:

a.		are not germane to the question to be amended;
b.		merely make the adoption of the amended question equivalent to a rejection of the amended motion;
c.		purposes to change one form of an amendment to another, and
d.		would have the effect of converting one parliamentary motion into another.
