6-letter words with O as the 1st letter and A as the 4th letter

The pattern is O _ _ A _ _, and 59 tournament-dictionary words fit it. Familiar examples include OBTAIN, ORGANS, and OCEANS, but only eight matches rank as common by English frequency. This is a narrow clue set: the fixed letters leave room for ordinary terms and less familiar entries.

Quick facts about this O-and-A pattern

• Exactly 59 six-letter entries fit O _ _ A _ _ across the tournament dictionaries counted here.
• Only eight matches rank as common by English frequency, so many entries are specialist vocabulary.
• Final S is the most frequent ending, with 20 matches; E comes next, with 12.
• OXCART, OCCAMY, and OXGANG each score 15 points before premium squares.

Which letters most often finish these words?

Twenty of the matches end in S, while 12 end in E. Those are the strongest final-letter clues once O and A are fixed; the next most common ending is T, with six words.

OBTAIN, ORGANS, OCEANS, and OSCARS show how much the middle letters can vary. Each fits O _ _ A _ _, but their endings differ, so don't let the fourth-position A dictate your final-letter guess.

All 20 entries are defined, and Collins alone contains the full set; ENABLE has 14 and NWL2023 has 16. That makes OPENED and ORANGE safer starting points than assuming every candidate crosses editions. Endings separate natural forms such as OZONES from the less familiar score leader, giving you a practical way to use the last revealed letter.

OXCART, OCCAMY, and OXGANG lead the raw scoring choices at 15 points each; OXGATE, OXLAND, and OXGALL score 14. The X drives these totals, so keep an eye out for a high-value letter rather than choosing only familiar vocabulary.

Dictionary coverage differs: Collins accepts 58 of these words, compared with 39 in NWL2023 and 36 in ENABLE. Only eight are common by frequency, so confirm your game's word list before relying on a less familiar play.

Changing the length shifts the count: the five-letter pattern has 29 matches, while the seven-letter version has 63. If your puzzle has room for another letter, compare those neighboring patterns instead of forcing a six-letter answer.
