What does the word therefor mean in the Shakespeares plays?

Answer 1

The main use of the word "therefore" in Shakespeare is to mean "therefore", which is just what you would expect, since he was writing in Modern English. There is an interesting line in Midsummer's Night's Dream where Demetrius says to Hermia:

"And if I could, what should I get therefore?"

Sometimes this is spelled "What should I get therefor." Either way, it means, "what should I get for it," or "what should I get as a result", or "what should I get as a consequence". "As a consequence" is the same as the ordinary meaning of therefore, and one can easily imagine Hermia responding, "If you could, I would therefore give you a privilege never to see me more."

Answer 2

In Shakespeare's plays, the word "therefor" is often used to mean "for that reason" or "consequently". It is a conjunction that serves to connect ideas or actions in a cause-and-effect relationship.
