(Can we date this quote?), Shakespeare, Richard III, I-iii:
- To both their deaths thou shalt be accessary.
- "This word, as used in law, is spelt accessory by Blackstone and many others; but in this sense is spelt accessary by Bouvier, Burrill, Burns, Whishaw, Dane, and the Penny Cyclopedia; while in other senses it is spelt accessory. In recent text-books on criminal law the distinction is not preserved, the spelling being either accessary or accessory." - Webster, 1913 Since that time this trend has accelerated.
