use the Oxford dictionary not the Black law dictionary!

by defining what dictionary I use to correspond with the court they expect that the black law dictionary is their dictionary and if you don't define what language you are speaking they are going to define that you are speaking the Black's law dictionary the Black's law dictionary is a very dangerous document for anyone who thinks that English.
The first thing you do in a public court is defined that you are using the Oxford or Webster dictionary not the black law dictionary
