Shakespearean English Explained
Shakespeare wrote in Early Modern English (c. 1590-1613). Key features: Thou/Thee = singular "you" (informal). Ye = plural "you". Thy = "your". Thine = "yours". Dost = "do". Hast = "have". Art = "are". Shalt = "shall/will".
Did Shakespeare actually write this way?
Yes, mostly. Shakespeare used these forms in his plays (1590s-1610s), which was normal English of that era. The language continued evolving — by the 1700s, "thou" had largely fallen out of use in most English dialects.
