Black's Law Dictionary
When law proceedings were written in Latin, if a word were significant though not good Latin, yet an indictment, declaration, or fine should not be made void by it; but if the word were not Latin, nor allowed by the law, and it were in a materini point, it made the whole vicious. (5 Coke, 121; 2 Nels. 830.) Wharton.
