Alliteration

Alliteration is the repetition of syllable-initial consonant sounds between nearby words, or of syllable-initial vowels if the syllables in question do not start with a consonant. It is often used as a literary device. A common example is "Peter Piper picked a peck of pickled peppers".
The word alliteration comes from the Latin word littera, meaning "letter of the alphabet". It was first coined in a Latin dialogue by the Italian humanist Giovanni Pontano in the 15th century.
Alliteration is used in the alliterative verse of Old English poems like Beowulf, Middle English poems like Sir Gawain and the Green Knight, Old Norse works like the Poetic Edda, and in Old High German, Old Saxon, and Old Irish. It was also used as an ornament to suggest connections between ideas in classical Latin, Greek, and Sanskrit poetry.
Today, alliteration is used poetically in various languages around the world, including Arabic, Irish, German, Mongolian, Hungarian, American Sign Language, Somali, Finnish, and Icelandic. It is also used in music lyrics, article titles in magazines and newspapers, and in advertisements, business names, comic strips, television shows, video games and in the dialogue and naming of cartoon characters.
There are several concepts to which the term alliteration is sometimes applied:
Poets can call attention to certain words in a line of poetry by using alliteration. They can also use alliteration to create a pleasant, rhythmic effect. In the following poetic lines, notice how alliteration is used to emphasize words and to create rhythm:
Alliteration can also add to the mood of a poem. If a poet repeats soft, melodious sounds, a calm or dignified mood can result. If harsh, hard sounds are repeated, on the other hand, the mood can become tense or excited. In this poem, alliteration of the s, l, and f sounds adds to a hushed, peaceful mood:

Literary alliteration has been used in various spheres of public speaking and rhetoric. It can also be used as an artistic constraint in oratory to sway the audience to feel some type of urgency, or another emotional effect. For example, S sounds can imply danger or make the audience feel as if they are being deceived. Other sounds can likewise generate positive or negative responses. Alliteration serves to "intensify any attitude being signified".
An example is in John F. Kennedy's Inaugural Address, in which he uses alliteration 21 times. The last paragraph of his speech is given as an example here.
"Finally, whether you are citizens of America or citizens of the world, ask of us here the same high standards of strength and sacrifice which we ask of you. With a good conscience our only sure reward, with history the final judge of our deeds, let us go forth to lead the land we love, asking His blessing and His help, but knowing that here on Earth God's work must truly be our own." — John F. Kennedy
Translation can lose the emphasis developed by this device. For example, in the accepted Greek text of Luke 10:41 the repetition and extension of initial sound are noted as Jesus doubles Martha's name and adds an alliterative description: Μάρθα Μάρθα μεριμνᾷς (Martha, Martha, merimnas). This is lost in the English NKJ and NRS translations "Martha, Martha, you are worried and distracted by many things."
