Where is a resource that lists words that can become another word with the addition of one letter while still maintaining the order of the letters? For example, adding an "I" to SLANDER creates the word ISLANDER. FRIGHT becomes FREIGHT.

I have found a variety of websites but they only offer 3-5 letter words. I'm looking for more challenging words.

You can use Qat with a query like



A and B are by default non-empty strings.


The concatenation of A and B forms a word.


The concatenation of A, any letter, and B forms a word.


The length of A is at least 0. This allows A to be empty. I haven't allowed B to be empty to forbid simple one-letter suffix additions like s, d, or r.


The total length of A and B is at least 7.

    $\begingroup$ What a neat site! A;A[!sdr];|A|=7- finds one-letter suffix additions, excluding s,d,r. Some fun ones are flamingO, crotchetY, directorY, and harmonicA. $\endgroup$ Mar 20, 2022 at 17:49

    $\begingroup$ This was a request for further information based on the answer received. Asking a separate question would lead to discontinuity. $\endgroup$ Mar 21, 2022 at 3:32

    $\begingroup$ @BobBaerker quite the opposite! You can ask a new question and link to this answer, and then a link will be automatically put into the sidebar for this page. Separately you can tag the new question with quinaplus increasing the connectivity between related questions! $\endgroup$ Mar 21, 2022 at 16:12

    $\begingroup$ Also the pattern in your comment is completely separate from the one in the answer... bobble is not amonishing you, but helping you follow the best practices here. Take a look at the tour, and read through How to Ask for more info $\endgroup$ Mar 21, 2022 at 16:14
