So we'd sit with these girls during school hours, and we told them, if they'd slip off, that we'd get away, and we'd go to to a spelling.
Because Elizabethan spelling was fluid, editors feel free to ‘modernize’ (correct) the spelling in the quartos and the Folio. But how is one to spell Rosencratz or Guildenstern, where the spelling varies, not only from text to text, but even within texts?.
Guildensterne and Rosincrance are F’s consistent spellings.
