The English language changes over time. Were that to be allowed in the English of Law and especially with legal terms would be equivalent to changing the Law. That must never be. These modern Editors have taken unjustifiable liberties with the definitions of some words in these newer version of Black's. For example, historically a driver is defined, in older Black's and others, as "One employed in conducting..." This version defines as driver as "A person who steers and propels a vehicle." While this later definition may be turn in street English it was never the intent or meaning in Legal English. To use this newer definition would abridge the unalienable rights of the individual. This is only one example and it alone is really disgusting. Keep or look for an older edition Law Dictionary.
