The King James Version of the Bible

During the Jacobean era (1603–1625) in 1611, The King James Version was published, largely based on Tyndale’s translation. It remained the standard Bible in the Church of England into the latter half of the twentieth century. [ref]

As a result, many fun archaic words persist in the public consciousness; for example, several interesting pronouns can be used with minimal loss of understanding.

U and V were the same thing

⟨u⟩ and ⟨v⟩ were not considered two distinct letters then but as still different forms of the same letter. Typographically, ⟨v⟩ was frequent at the start of a word and ⟨u⟩ elsewhere: hence vnmoued (for modern unmoved) and loue (for love). The modern convention of using ⟨u⟩ for the vowel sounds and ⟨v⟩ for the consonant appears to have been introduced in the 1630s. Also, ⟨w⟩ was frequently represented by ⟨vv⟩.
