7-letter words with Z as the 1st letter and O as the 5th letter

Z in the first spot and O in the fifth narrows a seven-letter rack to 24 entries, from ZOOLOGY and ZEALOUS to rarer terms such as ZELKOVA. Only one falls within the top 25,000 English words by frequency, so this pattern is far more useful for a constrained rack than everyday vocabulary. The entries also differ across Collins, NWL2023, and ENABLE.

At a glance: the Z___O__ pool

• Twenty-four entries match the fixed pattern Z___O__ in at least one tournament dictionary.
• Collins accepts 22; NWL2023 accepts 14, and ENABLE accepts 9, with overlap between lists.
• Only one entry ranks among the top 25,000 English words by frequency.
• Average score is 20.3; ZOOZOOS leads the individual scores at 25.
• Five entries end in S, compared with four ending in Y.

Which final letters appear most often?

S is the leading final letter, appearing in five entries; Y follows with four. D, E, and I each close three words, while K and O each close two.

One entry ends in A. When your board or rack supplies an ending, test S and Y early.

ZOOLOGY and ZEALOUS are recognizable anchors, but keep the fifth position fixed: each has O in that slot. ZELKOVA and ZIRCONS fit too. A familiar Z-word that shifts O one place no longer solves this clue.

How should you score 7-letter words with Z first and O fifth?

ZOOZOOS tops the score list at 25, ahead of ZIPLOCK at 24 and ZELKOVA at 23. ZUFFOLI and ZUFFOLO each score 22. ZOOTOMY, ZOEOFORM, ZOONOMY, ZEEDONK, and ZOMBOID each score 21, making them strong targets when the board supports a play.

A seven-tile play earns the standard Scrabble bingo bonus of 50 points, so see if your rack can use every tile in one turn. ZOOZOOS combines the top score with that full-rack possibility. The pool has just one common entry, though, so check your game's dictionary before committing to an unfamiliar word.
