Acrostic

ACROSTIC :At the age of seven Guru Nanak went to school and the schoolmaster wrote the alphabet on a wooden tablet for Nanak. After just one day Nanak copied the alphabet from memory and made an acrostic on the alphabet. The acrostic called the "Patti" or tablet in Rag Asa appears at page 432 in the Guru Granth Sahib, is as follows: 
"Raag Aasaa, First Mehl, Patee Likhee ~ The Poem Of The Alphabet:
One Universal Creator God. By The Grace Of The True Guru:
Sassa: He who created the world, is the One Lord and Master of all.
Those whose consciousness remains committed to His Service - blessed is their birth and their coming into the world. ||1||
O mind, why forget Him? You foolish mind!
When your account is adjusted, O brother, only then shall you be judged wise. ||1||Pause||
Eevree: The Primal Lord is the Giver; He alone is True.
No accounting is due from the Gurmukh who understands the Lord through these letters. ||2||
Ooraa: Sing the Praises of the One whose limit cannot be found.
Those who perform service and practice truth, obtain the fruits of their rewards. ||3||
Nganga: One who understands spiritual wisdom becomes a Pandit, a religious scholar.
One who recognizes the One Lord among all beings does not talk of ego. ||4||"

 about the general meaning of this word.
Acrostic is an memory aid to remember something.
An acrostic (from the late Greek akróstichis, from ákros, "top", and stíchos, "verse") is a poem or other form of writing in an alphabetic script, in which the first letter, syllable or word of each line, paragraph or other recurring feature in the text spells out a word or a message. As a form of constrained writing, an acrostic can be used as a mnemonic device to aid memory retrieval.
