7-letter words with S as the 1st letter and O as the 7th letter

That fixed ending makes the set unusually narrow: there are 30 tournament-dictionary entries, compared with 1,157 seven-letter words that start and end with S. Only two of these S-to-O words rank among the top 25,000 English words by frequency. Familiar picks such as shampoo and soprano sit beside specialist vocabulary, and Collins includes all 30 entries.

Which S-to-O words score highest?

SCHERZO leads the Scrabble scores at 21 points, with a Z worth a lot of that total. SQUACCO follows at 20, and SUBZERO scores 18. These are strong rack scores, but SCHERZO and SQUACCO are less familiar than SHAMPOO.

SMOKEHO reaches 16 points, while SYNCHRO and SHAKUDO each score 15. The useful scoring clue is the Z: when SCHERZO fits your rack, its value comes from the letter mix, not from being a long word.

When does this letter pattern fit?

Use the pattern when both ends are fixed and you need five letters between them. The 30 matches include everyday words such as SHAMPOO, plus terms such as SORDINO and SFUMATO. The small common-word count means a crossword or word-game rack may leave you with unfamiliar candidates.

The dictionary totals are not interchangeable: Collins has 30 matches, while NWL2023 has 23 and ENABLE has 22. A word accepted in Collins may not work in a North American game, so check your game's word list before committing to an obscure option.
