A final Z makes this a sharply limited word pattern: none of the nine entries ranks among the 25,000 most common English words. Five are built around hertz, from KILOHERTZ to PETAHERTZ, while KRUMMHOLZ stands apart as the highest scorer. These are tournament-dictionary entries, not a set of familiar everyday words.

9-letter words ending in Z at a glance

  • Nine tournament-dictionary words have nine letters and finish with Z.
  • KRUMMHOLZ tops the scoring list at 29 points.
  • KILOHERTZ scores 25, ahead of MEGAHERTZ at 24.
  • Five entries are hertz compounds; the other four are SLIVOVITZ, RHEUMATIZ, SLIVOWITZ and KRUMMHOLZ.

How many are accepted across word lists?

Collins includes all nine words, while NWL2023 includes eight and ENABLE includes six. That gap matters in tournament play: a word accepted in one list may not carry over to another.

The first letters offer a small clue when you are sorting candidates: K and S each begin two entries, while G, M, P, R and T begin one apiece. All nine share the final Z, so the starting letter and the middle pattern do most of the distinguishing.

Five of the nine are frequency-unit compounds: GIGAHERTZ, KILOHERTZ, MEGAHERTZ, PETAHERTZ and TERAHERTZ. The narrow theme is unusual for an ending-letter list, and it makes the hertz words a quick group to recognize without confusing them with the remaining four entries.

How to use 9-letter words ending in Z in a game

For a score-first play, check KRUMMHOLZ before the hertz compounds: its 29 points beat KILOHERTZ by four. The next tier includes MEGAHERTZ, SLIVOVITZ and SLIVOWITZ at 24 points each; GIGAHERTZ, PETAHERTZ and RHEUMATIZ each score 23.

Treat the score ranking as a starting point, not a promise of a legal play. The list has no common entries, and its vocabulary is specialized; confirming the spelling and dictionary fit is more important than reaching for the top score. For a broader choice of endings, compare the other nine-letter lists.
