6-letter words with F as the 5th letter and S as the 6th letter

Every entry follows the same pattern: five letters, then F, then S. The final pair makes this a sharply defined clue, but the words before it vary widely. Only 8 are among the most common English words, so expect a mix of familiar plurals such as CLIFFS and less everyday game vocabulary.

The pattern at a glance

• There are 74 qualifying words, each ending in the fixed letter pair FS.
• CHIEFS, CLIFFS, PROOFS, and BRIEFS are recognizable examples from the list.
• Only 8 entries rank among the top 25,000 English words by frequency.
• S is the first letter in 23 matches; G is next with 12.
• QUIFFS and QUAFFS lead the scoring list at 21 points apiece.

Which words fit the F-and-S ending?

Several entries are familiar plural forms: CHIEFS, CLIFFS, PROOFS, BRIEFS, MOTIFS, and STAFFS. Others, including STUFFS, BLUFFS, SNIFFS, and SCOFFS, pair the ending with an everyday verb form. These examples show why the letters before FS matter when you are checking a clue.

The opening letter is not evenly spread. S starts 23 words, nearly twice as many as G, which starts 12; C begins 7 and P begins 6. If your clue leaves the first letter open, testing S first covers the largest single starting-letter group, but it still accounts for less than half of all matches.

Scores and dictionary differences

• QUIFFS and QUAFFS each score 21 points, while WHIFFS scores 18; the Q and high-value letters drive those totals.
• HOWFFS and QUOIFS also reach 18, so a less familiar word can outscore a common plural.
• Collins includes 73 matches, compared with 53 in NWL2023 and 50 in ENABLE; those counts overlap rather than add up.
• For 6-letter words with F fifth and S sixth, dictionary coverage is the catch: a match in one list may not appear in another.
