If a word has a certain property, I call it a Shifting Word™.
You can use the examples below to find the property:
Here's a CSV version:
ace,jack army,navy commute,common effort,stress egg,apple grumpy,sad influx,income Knox,fort moth,bug obey,allow solo,alone wonky,wobbly wrens,crows yolk,white
Can you tell me the rule?
Most of the Shifting Words™ are short. In fact, no English word (even an invented one!) may contain more than 7 letters. However, other languages like French, Russian, Thai etc. may possibly have longer words.
