Peer review 2010

 

The LIST Council has been asked by ALOA and others to complete what would amount to a Dictionary for Locksmiths. We have begun that work and are pleased to submit this installment of the remaining terms that have been identified as specific to our industry.  Terms in this listing marked with an asterisk indicate current terms from the Locksmith Dictionary that have a revised definition proposed.
 
When making a definition of a term, we applied the following rules to the term:
 
1. Is the term listed in "Webster"?
2. Is the definition there the same meaning used in our industry?
 
To us, "Webster", means a typical pocket dictionary, which could be obtained easily, and on short notice, from any grocery store which has a pocket book display. If the answer to either of the questions above was no, we felt the term must be in our dictionary, otherwise it was common usage which anyone could define.
 
Because there is generally more than one term in use from one geographic area to another, we established the most popular term that most closely describes what it means as the "primary" term to be defined, unless it has different opposing definitions.  All other terms with the same meaning become secondary terms and are only listed in the appendix. With that established, the definitions have to meet the following rules:
 
1. It must describe the subject of the term without graphics.
2. It must describe ONLY the subject of the term.
3. The term should not be used in the definition.
 
If you have a technical objection to any definition, please bring it to the attention of the publisher of this listing, or a member of the LIST Council for review before November 15, 2010.
