E · A · R · S · T
The five commonest letters. E is in 49% of the pool — nearly every other word.
S · C · B · T
The commonest openings. S alone starts 199 of them.
E · Y · T · R
The commonest endings. 245 words end in E — more than one in six.
31%
Have a letter twice — 422 words. Far more than most players expect, and the single commonest way a guess is misread.
110
End in S, out of 1,377. Opening with a plural spends a letter on an ending that is rarely there.
Q · J · Z · X
The rarest. Q appears in just 13 words, so ruling it out early is worth almost nothing.
