Have you ever noticed that the words dad, ewe, pop, sexes and redder all read exactly the same backwards? They are called 'palindromes' (Polish: palindromy). These can also be sentences or utterances (even longer pieces). Here I list a few famous examples:
Madam, I'm Adam. Was it a cat I saw? Able was I ere I saw Elba. A man, a plan, a canal - Panama. Doc, note, I dissent. A fast never prevents a fatness. I diet on cod.
And a few Polish ones:
Zagwiżdż i w gaz, Zaradny dynda raz, Raz czart - raz czar, A to kłamał koń, okłamał kota, Ile Roman ładny dyndał na moreli?
There are also so called 2D palindromes in which every row and column reads as a word in both directions. There is a selection of 3x3, 4x4, 5x5 and 6x6 palindrome squares in English.
G | E | L |
E | Y | E |
| L | E | G |
Maybe you can try to create your own palindromes?
