9-letter words ending in O

An O at the end narrows the search to a small, distinctive set: only 152 tournament-dictionary entries match this length and ending. Many are borrowed or specialized terms, so portfolio and superhero stand out among less familiar choices such as taekwondo and imbroglio. Just 3 entries meet the common-word cutoff, making dictionary coverage worth checking before you play.

Which O-ending words score the most?

PAVONAZZO is the standout scorer at 32 points, while PAPARAZZO and PIZZICATO each reach 31. PIZZAIОLO follows at 29, and CHECHAQUO scores 28. These spellings pack valuable letters into one play, so check your rack before settling for a familiar, lower-value word.

The starting-letter pattern is unusually concentrated: S, C, and P account for the leading groups, with 26, 24, and 22 matches respectively. Try those openings first when your rack supports them. The highest scorer is not necessarily the easiest play; PAVONAZZO and CHECHAQUO are much less familiar than portfolio or manifesto.

How widely do these words appear in game dictionaries?

Dictionary coverage is uneven. Collins includes 148 of the entries, compared with 97 in NWL2023 and 70 in ENABLE; those counts overlap, so they do not add up to separate groups. A word accepted in one list may be rejected in another, especially among specialized terms.

Only 3 matches count as common, and none are everyday choices for every rack. Portfolio, armadillo, and pistachio give you more recognizable starting points, while words such as siciliano and majordomo are less likely to come to mind quickly. Check your game's word list before relying on an unfamiliar entry.
