There’s one other similar conundrum that has always intrigued me:
What 3-letter suffix can be added to the most letters of the alphabet to make valid 4-letter words?
True word nerds just use their brains and knowledge of language. Guys like me use VBA.
Warning: This code takes forever to run. Run it at your own risk.
Dim i As Long, j As Long, k As Long
Dim lStart As Long
Dim sWord As String
For i = 97 To 97 + 25
For j = 97 To 97 + 25
For k = 97 To 97 + 25
For lStart = 97 To 97 + 25
sWord = Chr$(lStart) & Chr$(i) & Chr$(j) & Chr$(k)
If Application.CheckSpelling(sWord) Then
Sheet1.Cells(Sheet1.Rows.Count, 1).End(xlUp).Offset(1, 0).Value = sWord
There was only one with 13 matches.
The array formula in Column B is
The three-letter suffixes with 12 hits: aps, ats, ear, est, ill, ock, and ops. There were 1,145 unique suffixes, 644 of which only had one match.
