The term IN ORDER THAT can be broken down into two parts: SO (2 letters) and SOASTO (6 letters). SO is an abbreviation for the word 'SO that' which is used to indicate a purpose or result. SOASTO is an acronym for 'SO as to' which is also used to indicate a purpose or result. Both of these terms are used to express the idea that something should happen in order for something else to happen. They are often used in legal documents and contracts to indicate that certain conditions must be met in order for an agreement to be valid.
