The Elizabethan Era existed during the reign of Queen Elizabeth I and the language of the time was much different than today's English language.
Many words used in the Elizabethan language are no longer in use. Other words have replaced them or the original meaning and use of the words are no longer required
An amusing example of words now 'extinct' in the modern English language is 'gong'. The Elizabethan word 'gong' meant dung. The men whose job was to empty and dispose of the waste from the privies (toilets) were called 'Gong Farmer.
The number of words used in the Elizabethan Language were constantly developing during Elizabethan times - their vocabulary was expanding.
The Elizabethan language and vocabulary had not been formalized. New words were being invented. Elizabethan dictionaries were not available. Elizabethan words were therefore written in a variety of different formats.
