# What is a Re-Tileable Word™?

This is in the spirit of the What is a Word/Phrase™ series started by JLee with a special brand of Phrase™ and Word™ puzzles.

If a word has a certain property, I call it a Re-Tileable Word™.

You can use the examples below to find the property:

$$\begin{array}{|c|c|} \hline \bbox[yellow]{\textbf{Re-Tileable Words™}}&\bbox[yellow]{\textbf{Un-Re-Tileable Words™}}\\ \hline \text{KALE}&\text{CHARD}\\ \hline \text{ROOSTER}&\text{COCKEREL}\\ \hline \text{KARMA}&\text{FORTUNE}\\ \hline \text{SALMON}&\text{MACKEREL}\\ \hline \text{TEST}&\text{QUIZ}\\ \hline \text{DREAM}&\text{NIGHTMARE}\\ \hline \text{FAST}&\text{QUICK}\\ \hline \text{CRAFT}&\text{ORIGAMI}\\ \hline \text{VIEW}&\text{SCENERY}\\ \hline \text{ORGAN}&\text{GLAND}\\ \hline \text{SCORE}&\text{MARKS}\\ \hline \text{EROTIC}&\text{SEXUAL}\\ \hline \end{array}$$

For those without MathJax, or if you want to pop this into a spreadsheet, here is a CSV version:

KALE, CHARD
ROOSTER, COCKEREL

• I was thinking along the same lines, except that I used this random wordsmith.org/anagram/advanced.html anagram solver which did not give anything useful for KARMA. Then I dropped the idea. – Matsmath Sep 20 '16 at 7:37
