7-letter words with O as the 1st letter and X as the 2nd letter

Every match begins OX, but the rest of the set is far from everyday vocabulary: none ranks among the 25,000 most common English words. Chemistry supplies recognizable entries such as OXIDASE, OXIDANT, and OXALATE, while OXBLOOD and OXFORDS look more familiar outside a lab. Counts vary by tournament lexicon, so check your game's word list before playing an obscure form.

The OX pattern at a glance

• All 32 seven-letter matches start with the fixed pair OX.
• Collins accepts 29; NWL2023 accepts 23, and ENABLE accepts 19.
• OXIDIZE is the top scorer at 24; OXAZINE and OXAZOLE each score 23.
• Thirteen entries end in S, more than any other final letter; E follows with nine.
• Only 27 matches have definitions, and none is common by the frequency cutoff.

Which OX words score highest?

OXIDIZE scores 24 points, one ahead of OXAZINE and OXAZOLE at 23 each. OXYPHIL scores 22, while OXYACID scores 20. The OX opening can be misleading: the strongest plays rely on the less familiar Z and Y, not just the first pair.

OXIDASE, OXIDANT, OXIDIZE, and OXIDISE show a spelling split: the set includes both -IZE and -ISE forms. OXALATE adds another recognizable chemistry term, but the zero common-word count warns against treating familiarity with OX as proof that a seven-letter play is likely.

Ending letters narrow choices quickly: S closes 13 words and E closes nine, while D and T each close three. Need an E? OXAZINE, OXAZOLE, and OXIDIZE all fit; the S-ending group is larger if your rack points that way.

7-letter words with O as the 1st letter and X as the 2nd letter

• Treat OX as a fixed opening, then sort the remaining letters around endings S, E, D, or T.
• Keep OXIDIZE, OXAZINE, and OXAZOLE in mind for scoring; they lead at 24, 23, and 23 points.
• Don't assume a familiar-looking form is common: none of these words reaches the frequency cutoff.
• Compare the 32-word OX group with O-V and O-U patterns before committing a turn to an obscure rack.
