From The Taming of the Shrew.

Middle English is used in Shakespeare's works (the transitional period from old English to modern English, which can also be called early modern English), and many words are different from those we use now. Not very modern.

Can I compare you to summer? There, they are actually old English, meaning "you".

"Ta'en" may be a simplified usage of take, in order to take care of the needs of dramatic language.

Word for word translation, there is no gain (benefit) growth, where can there be fun (very weird literal translation)

Free translation is what you mentioned in your question, which is widely circulated that "knowledge must meet your own interests in order to benefit"
