6-letter words with O as the 4th letter and S as the 5th letter

The pattern locks the middle of each answer into O-S, leaving four letters to distinguish words such as ACROSS, CHOOSE, EXPOSE and WHOOSH. Just 8 matches count as common by frequency, so expect a mix of everyday vocabulary and rarer entries. Endings are lopsided too: E is the final letter for 48 words.

The O-S pattern at a glance

• There are 103 tournament-dictionary words with O fourth and S fifth.
• ALMOST, ACROSS, CHOOSE and EXPOSE are recognizable examples.
• A final E is especially frequent, appearing in 48 matches.
• Collins has 101 matches, compared with 80 in NWL2023 and 74 in ENABLE.

Which familiar words fit the O-S sequence?

ALMOST and ACROSS are easy anchors: both place O-S in the required slots, but their openings make the pattern less obvious at a glance. CHOOSE, EXPOSE, OPPOSE and IMPOSE offer another cluster, with the same ending and different first three letters.

REPOSE, DEPOSE and MOROSE end in E, while WHOOSH ends in H and UTMOST ends in T. After E, H closes 15 matches and T closes 14, so those are the next endings to try. The 48 E-ending matches make that finish the strongest place to start when the final square is unknown.

For Scrabble scoring, ZYGOSE leads these examples at 19 points. KYBOSH scores 18, and XYLOSE and HEXOSE each score 16. Those less familiar words are worth checking against your rack and board; a high tile score matters only if the word is accepted in your game.

Dictionary coverage is the main limitation: Collins includes 101 matches, while NWL2023 includes 80 and ENABLE includes 74. Not every candidate works across all three lists, so check your game's word list before playing. For a more familiar option, ALMOST is among the recognizable fits.
