7-letter words with S as the 3rd letter and F as the 7th letter

This is a tight clue set, with no matches among the 25,000 most frequent English words in the frequency measure used here. The strongest recognizable entries are MASTIFF, DISTAFF, CASTOFF, and DUSTOFF. Each places S in the third slot and F at the end, but the words differ in their openings and game scores.

7-letter words with S as the 3rd letter and F as the 7th letter

• Exactly 10 tournament-dictionary words fit the two fixed letter positions.
• All 10 matches end in F; no other final letter appears.
• MASTIFF and CASTOFF tie for the top score at 15 points each.
• D and R are the most common first letters, with three words apiece.
• Collins includes all 10 matches; ENABLE and NWL2023 each include seven.

Which words fit this S-and-F pattern?

The opening letters divide into a small group: three words start with D, three with R, and one each with C, H, M, and P. That makes the first letter a useful extra filter once your puzzle confirms S in position three and F at the end. DISTAFF and DUSTOFF are two D starters; RESTUFF and RESTAFF show the R group.

The vocabulary is less familiar than the letter pattern suggests. None of the matches is common by the frequency cutoff, and only five have definitions in the available count. Treat this as a constrained word-game search rather than everyday vocabulary; a possible fit still needs to match your game’s dictionary.

Which matches score highest, and where are they accepted?

MASTIFF and CASTOFF each score 15 points before board bonuses, followed by DISTAFF and DUSTOFF at 14. Hisself, RESTUFF, RESTAFF, and RESTIFF score 13 apiece. The average score across the set is 13.3, so these fixed letters come with solid tile value even when the words are obscure.

Collins recognizes more of these matches than either ENABLE or NWL2023. Do not assume that a word accepted in one list works in another. For a practical solve, check the exact letter slots first, then confirm the word in the dictionary used by your game.
