Shakespeare uses the word "sympathy" to mean sympathy. Vide this example from 2 Henry VI:
I can express no kinder sign of love
Than this kind kiss. O Lord, that lends me life,
Lend me a heart replete with thankfulness!
For thou hast given me in this beauteous face
A world of earthly blessings to my soul,
If sympathy of love unite our thoughts.
You have my deepest sympathy.
It's like a curtain. The word Shakespeare uses is "arras" which means, well, it means a curtain.
Shakespeare does not use the word "e'ev". Ever. It doesn't exist. It's a typographical error in your course materials.
Shakespeare wrote in English, the same language I am using now. There is no such language as "Shakespearean language" or "Shakespeare language". It's English. A word like "then" is a building block of the English language and always means "then" when Shakespeare or any other English speaker uses it.
He only uses the word twice, once in Coriolanus and once in Love's Labour's Lost. Both times it means exactly what it means nowadays--a little fish.
Sympathy
Shakespeare did use the word "confuse" but he liked the word "confound" better. Friar Lawrence uses it when Romeo and Juliet meet to be married.
Eshiberaa is an African Luhya word that means "sympathy" in English language.
When does he use it? He certainly uses "been" (which means "been"). An apostrophe indicates that some letters have been left out: "possess'd" means "possessed", "wond'ring" means "wondering". What word might this be? "Between"? I have never heard of Shakespeare writing "between" as "b'een"
William Shakespeare sometimes uses the word gi in his plays. This word has the same meaning as the word give.
You are thinking of the word "fiery" which means like fire or full of fire. There is no such word as "firey"; not then nor now. Often Shakespeare uses the word "fiery" to describe someone's temper. Saying someone is fiery-tempered is another way of saying he's hot-tempered.
Shakespeare wrote in English. "The" means exactly the same when he used it as it does when you use it.
