Acrostic

Acrostic is a composition in the form of a poem, puzzle, or any other form of writing that is written by using all the letters or syllables of a word or an expression in which they appear in a particular order.

Each line of the composition contains a letter or syllable usually in the beginning, but can also be placed at other places in a particular order.

For example, the poem in English written by Edgar Allan Poe, entitled "An Acrostic". It is written by using the letters in the word 'Elizabeth'. Each line begins with a letter of the word in a sequence.

Elizabeth it is in vain you say
"Love not"—thou sayest it in so sweet a way:
In vain those words from thee or L.E.L.
Zantippe's talents had enforced so well:
Ah! if that language from thy heart arise,
Breath it less gently forth—and veil thine eyes.
Endymion, recollect, when Luna tried
To cure his love—was cured of all beside—
His follie—pride—and passion—for he died.

There can also be multiple acrostic, that is composed by using a letter or syllable more than once in a particular order.
