7-letter words with O as the 2nd letter and Z as the 5th letter

The fixed shape is _O__Z__, so both known letters sit inside the word rather than at either end. The matches range from familiar horizon to rarer forms such as polyzoa and wootzes. Six begin with I and nine finish with S, which gives you strong letter clues when several blanks remain.

The O-and-Z pattern at a glance

• There are 19 tournament-dictionary matches for the seven-letter pattern _O__Z__.
• Only one match is common among the 19 words.
• I is the leading first letter, starting six matches.
• S is the leading final letter, ending nine matches.
• Polyzoa, coryzal, and coryzas tie for the top score at 21.

Which words fit O second and Z fifth?

Horizon is the standout familiar example, but it is not the only recognizable shape. Ionized, iodized, ionizes, ionizer, and topazes also fit, with O in slot two and Z in slot five. Those shared positions can make the pattern easier to scan than a long string of blanks.

The opening letters offer another filter: six matches start with I, three with C, and two each with B, D, and H. If your first tile is I, try ionized, iodized, ionizes, or ionizer before reaching for a less familiar entry. Polyzoa and soyuzes show how far the remaining options stretch.

Which matches score highest, and what should you watch for?

Polyzoa, coryzal, and coryzas each score 21, ahead of horizon, hoatzin, wootzes, and soyuzes at 19. Iodized, topazes, and borazon score 18. The top-scoring words are not the easiest to recognize, so a strong board score does not make them dependable guesses.

The dictionary coverage varies: Collins includes all 19 matches, NWL2023 includes 15, and ENABLE includes 13. Check your game's word list before playing an unfamiliar form. For solving the pattern, keep the fixed O and Z in place, then use the starting-letter split or the nine S endings to test candidates.

The 7-letter words with O as the 2nd letter and Z as the 5th letter are a narrow set, not a list of everyday vocabulary.
