Compose word-level palindromes from a lexicon, mirror or minimally edit any text into one, take a sentence apart, and hunt palindromes in the integers.
Words are chosen so the whole letter stream reads the same both ways, the way a man a plan a canal panama does.

The composer draws on this list. Replace it with your own — one word per line, or any whitespace separated text.
Words whose reversal is another word — the raw material of two-way sentences.
Use ? for one letter, * for any run. Try ?a?a? or re*er.
