Writing acrostic poems and mnemonic sentences
An acrostic hides a word in a poem: read the first letters of the lines downwards and they spell it out. Name poems, where a child’s name runs down the page, are a classroom favourite; poets have used acrostics to hide dedications for centuries. The same first-letter trick powers mnemonics, sentences that help you remember lists in order. This helper supports all three jobs.
Writing an acrostic
Type the word or name and each of its letters appears as the start of a line, with six word ideas beginning with that letter. The ideas are common English words, so they are easy to build a line around. Good acrostic lines usually say something about the word itself — for HOPE, lines about light, patience or tomorrow — rather than just starting with the right letter. Copy the outline to paste it into a document or worksheet.
Checking a poem
Paste a finished poem with one line per letter. The checker reads the first letter of each line and tells you whether they spell the word; lines that start with the wrong letter are marked with the letter they should have. It also reads the last letters downwards. If those spell the word too, you have written a double acrostic, a rarer and harder form. A poem whose last letters spell a word is called a telestich.
Mnemonic sentences
Switch to the mnemonic helper and enter a list of things to remember, one per line, in order: the planets, the colours of the rainbow, the stages of mitosis. The tool shows the first letters and offers word ideas for each, so you can build a sentence such as “Richard Of York Gave Battle In Vain” for red, orange, yellow, green, blue, indigo and violet.
Where the word ideas come from
The suggestions are drawn from the Dale–Chall list, about 3,000 words that most fourth-graders know, used in readability research. That keeps ideas simple and familiar, which suits children’s poems and memorable mnemonics. Proper names, rare letters such as x and specialist words need your own vocabulary.
In the classroom
Name poems are a gentle start to poetry writing, as each line is a small, achievable task. Acrostics also work for revision: a poem about PHOTOSYNTHESIS that explains the process line by line. Mnemonics help with lists in science, music and history. The checker gives instant feedback on the letter rule, so feedback can focus on the words.

A worked example
For the word SUN, the outline shows S, U and N, each with six word ideas to build a line on. A finished poem might read “Shining over every field, / Up before the farmers wake, / Never late and never tired.” Pasted into the checker, the first letters read SUN and the notice confirms it. The last letters read D, E and D, so it is not a double acrostic. If the second line had started with “Over”, the checker would mark it and show that it should start with U, which is the most common slip when lines are rewritten during editing.
