The other day, I saw the following brain-teaser posted on Reddit:

along with the claim that “Startling” is the only 9 letter word where you can remove one letter at a time and still have a word.

Let’s see if that’s true using IPython and a long list of words from http://www.mieliestronk.com/wordlist.html

[ed. note in 2018 – this link expired. I’m not quite sure where it went. Sorry!]It turns out that there are seven words of length 9 that match this property,  and one word of length 10: “Splittings” (actually an incredibly relevant word to this problem).

Just goes to show: don’t believe everything you read on the internet 😉
