Compound words carry the list

Most entries join two familiar words. Back ends quarterback, diamondback, leatherback and stickleback; work ends plasterwork, latticework and leatherwork; doublespeak and doublethink end in words you already know.

That shape is what makes the list readable. You do not need to recognise candlestick or cheesesteak as single units, only the two pieces that meet before the final K.

Compounds also explain the length: two shorter words pushed together reach eleven letters far more easily than one long root.

Why K rarely ends a long word

Final K is common in short words and rare in long ones. The seven-letter list holds 419 K-endings and the eight-letter list 499, but eleven letters reach only 64.

Compare the endings above it: S closes 12,484 eleven-letter words, and G, E and D each pass two thousand. K trails the whole field until the last few letters of the alphabet.

Playing a K-ending compound usually means trusting a word you have never written, which is where the dictionary line matters.
