|Play||Romeo and Juliet|

Mercutio (pron.: //, mur-KYEW-shee-oh) is a fictional character in William Shakespeare's 1597 tragedy, Romeo and Juliet. He is a close friend of Romeo and Benvolio, and also a blood relative to Prince Escalus and Count Paris. As such, being neither a Montague nor a Capulet, Mercutio is one of the few in Verona with the ability to freely float around both houses. The invitation to Capulet's party states that he has a brother named Valentine.
Though often fun-loving and witty, the latter of which shows through in his Queen Mab speech in the first act, Mercutio's sense of humor can at times be facetious or even coarse, much to his friends' annoyance. Moreover, he is very moody and can be given to sudden outbursts of temper, one of which sets a key plot development in motion.
Role in the play 
One of Romeo's closest friends, Mercutio entreats Romeo to forget about his unrequited love for a girl named Rosaline and come with him to a masked ball at Lord Capulet's estate. There, Mercutio and his friends become the life of the party, but Romeo steals away to Juliet, Capulet's daughter, with whom he has fallen in love, and fell out of love with Rosaline. When Mercutio sees Romeo the next day, he is glad to see that his friend is his old self again, and encourages Romeo to meet again with Juliet, all the while making bawdy jokes at her Nurse's expense.
After Romeo receives a death threat from Tybalt, Mercutio expects Romeo to engage Tybalt in a duel. However, Romeo refuses to fight Tybalt, as Tybalt is Juliet's cousin and therefore his kinsman. Mercutio is incensed at his friend's "vile submission", and decides to fight Tybalt himself. Romeo, not wanting his friend or his relative to get hurt, intervenes, causing Mercutio to be killed by Tybalt stabbing "under [Romeo's] arm."
Before he dies, Mercutio curses both the Montagues and Capulets, crying "a plague on both your houses!" He makes one final pun before he dies: "Ask for me tomorrow, and you shall find me a grave man...." A grief-stricken and enraged Romeo kills Tybalt, thus leading to Romeo's banishment from Verona and beginning the tragic turn of events that make up the rest of the play.
Name origins 
The name Mercutio was present in Shakespeare's sources for Romeo and Juliet, but his character was not well-established, and he was even presented as a romantic rival for Juliet. Mercutio's name is related to the word "mercurial," meaning, "having an unpredictable and fast changing mood," an accurate description of Mercutio's personality. The word "mercurial" itself derives from the ancient Roman messenger god Mercury (Greek: Hermes). Another possible origin of the name is an earlier (1530) adaption of the same Italian folk story from which Arthur Brooke and Shakespeare drew their main sources, written by Luigi da Porto: in his version, which is the first to actually contain the names "Romeo" and "Giulietta", he introduces a character named Marcuccio.
Mercutio's death 
Earlier versions of the story painted a different picture of the chain of events leading to Tybalt's death, leaving Mercutio out of the picture completely. Arthur Brooke's The Tragical History of Romeus and Juliet, as well as William Painter's 1567 version of the story, both left the entire episode solely to Romeo and Tybalt. In both stories, Tybalt attacks the peace-pleading Romeo with such force that he is forced to take up the sword to defend himself. He is then banished rather than executed because the killing was provoked. In 1672, English poet John Dryden wrote, "Shakespeare show'd the best of his skill in his Mercutio, and he said himself, that he was forced to kill him in the third Act, to prevent being killed by him."
The addition of Mercutio into the fray increases the tension, and Tybalt is seen as a slightly more peaceful character than in previous versions, as Mercutio is disgusted by the fact that Tybalt continues to search for a quarrel with Romeo, when Romeo is trying to bring peace between them. Mercutio hurls insults and taunts at Tybalt, and draws the sword first, in reaction to Tybalt's insults, which are directed to Romeo.
Mercutio's death in Act III, scene I is the pivotal point of the play, which up to this point is relatively light-hearted. Mercutio's death is sudden, and makes death a dark reality for several characters, causing a domino effect of tragic fate that leads ultimately to the tragic climax.
