Shakespeare's success as a playwright was greatly influenced by his use of language. His use of puns, wordplay, and blank verse demonstrated his command of the English language.

He had an unmatched capacity for using language to evoke strong emotions and intricate concepts. He was adept at using words to evoke a sense of place and to engross his readers in the narrative.

His implementation of blank verse was especially ingenious since he was able to employ it to give his plays a feeling of rhythm and an increased sense of drama. 

His use of humor and puns was also quite effective since they provided him with a way to add comedy and establish sarcasm. Shakespeare's choice of language played a significant role in the play's lasting popularity.

blank verse:

Instead of rhyming, blank verse adheres to a precise meter, usually iambic pentameter, that is composed of five pairs of alternating stressed and unstressed syllables.

In his plays, Shakespeare frequently used blank poetry. As a result, he was able to give his characters natural and effortless poetic speech.

The absence of rhyme also gives the text an open-ended quality by letting the characters express their ideas in full without being constrained by complex rhyming patterns. Here's an extract from Romeo's speech in "Romeo and Juliet".

“But soft, what light through yonder window breaks?

It is the East, and Juliet is the sun.

Arise, fair sun, and kill the envious moon,

Who is already sick and pale with grief

That thou, her maid, art far more fair than she.”

Shakespeare typically saves his most somber and eloquent remarks for blank verse. In comedies, rhymed verse is more common.

Jokes and word games:

Shakespeare was a virtuoso at conveying his ideas and topics using wordplay and puns. In his era, no one could match his talent to create smart jokes and double entendres. He frequently employed puns to make a point about his characters or the story as well as to provide a hilarious effect.

“Better a witty fool than a foolish wit” – Twelfth Night.

Feste's puns are employed in "Twelfth Night" to poke fun at the other characters and to highlight how dumb their actions are. Feste is a subversive figure who, despite being portrayed as a fool, can highlight things other characters fail to notice because he lives outside of conventional society.

Shakespeare often employed puns to provide an element of irony, as seen in the play "Macbeth," where Macbeth's references to death anticipate his death. As in "Romeo and Juliet," where Romeo makes puns about Juliet's name to build suspense before their meeting, he too employs wordplay to create an impression of tension or suspense. Puns and wordplay played a significant role in Shakespeare's writing and enhanced the depth of his language.

Early modern English language:

A significant linguistic shift occurred during the Elizabethan Period. Many different dialects and regional accents were being used at the time, and the English language was still in transition. 

The language of the court and the theatre was greatly influenced by the development of a new standard form of English during this time.

Shakespeare was an expert in the newly developed language, and his works show how adept he was at evoking strong and vivid imagery. He was also skilled at using wordplay, puns, and creative blank poetry to take advantage of the linguistic shifts of the day.

Shakespeare's linguistic style was influenced by the developments taking place in Elizabethan England. He was capable of using both the expanding language that was at his disposal and the novel expression styles that were developing.

His plays demonstrate a command of both the language of everyday life and the language of the court. He was able to bring both of these together to develop a distinctive and potent mode of expression. 

New terms and phrases:

Shakespeare was a pioneer in the creation of new words and expressions that are now a part of the English language. His writings are replete with recently created words like "eyeball," "swagger," and "lackluster," all of which have entered regular speech.

Shakespeare coined several expressions, including "a heart of gold." Aside from that, he coined other idiomatic expressions still in use today, including "in a pickle," "heart of gold," and "break the ice." It is impossible to picture what the English language would be like without his services because of his enormous impact on the language.

Shakespeare contributed more than just words and phrases to the English language. He also created many literary tropes and strategies, including the use of extended metaphors, oxymorons, and rhetorical inquiries.

Because of how effectively he used language, it has been studied and imitated for generations. Numerous languages have translated his writings, and his impact on language continues to be recognized today.
