7-letter words with S as the 2nd letter and O as the 4th letter

The fixed positions leave 29 matches, but the opening letter is far from fixed: E begins 11, O begins 9, and A begins 7. Only one entry is common by frequency, so familiar picks such as OSMOSIS sit beside rarer forms, though twenty matches have definitions. Treat the pattern as a narrow clue, not a promise of familiar vocabulary.

At a glance: counts, endings, and top scores

• Exactly 29 tournament-dictionary words match the S-second, O-fourth pattern.
• E starts 11 matches; O starts 9 and A starts 7.
• Fourteen matches end in S; E and D finish 5 and 4 words.
• OSMOTIC, PSIONIC, and ASCONCE tie for the highest listed Scrabble score: 11.

Which words fit _S_O___?

The second tile is S and the fourth is O. OSMOSIS, ESPOUSE, and ASTOUND show how different the surrounding letters can be, even though each shares those anchors. The examples also cover varied openings: O, E, and A lead the biggest groups.

OSMOSIS and OSMOTIC both open with OS and keep O in the fourth position, but their endings separate them. First letters tell a sharper story than the middle clue alone: E leads with 11, O follows at 9, and A has 7; P and T contribute one word apiece.

The parallel seven-letter pattern with E in position two and O in position four has 349 matches. S is a much sparser choice for that slot, so checking the first and last letters can quickly narrow your candidates.

Endings bunch up even more strongly: 14 of the 29 matches close with S. E ends 5, D ends 4, and R ends 3, while C appears twice and L once. A final S is a practical sorting clue, though it still leaves several endings in play.

Only one match is common by the frequency measure, so many candidates will feel unfamiliar outside word games. Collins includes 28 entries, compared with 20 in NWL2023. Check your game's word list before committing to a less familiar form; the dictionary split means the full set is not accepted everywhere.
