6-letter words with E as the 4th letter and F as the 5th letter

The fixed E-F pair leaves only 20 tournament-dictionary entries, and their endings are unusually lopsided: 10 finish in Y while 6 finish in S. Most are not everyday vocabulary; just 2 fall within the top 25,000 English words by frequency. Treat this as a pattern-solving list, not a set of likely everyday guesses.

6-letter words with E fourth and F fifth: key facts

• Twenty entries match the E-fourth, F-fifth pattern across tournament dictionaries.
• Y is the final letter in 10 matches; S is last in 6.
• T begins 4 words, more than any other starting letter.
• HUMEFY scores 17, the highest Scrabble value in the group.

Which endings appear most often?

Only 2 of the 20 matches are common by the top-25,000 frequency cutoff, so familiar-looking forms are the exception. CHIEFS and BRIEFS stand out as recognizable plurals, while BEREFT gives the pattern a familiar non-plural option.

Endings explain the list's shape. Ten words finish in Y, including RAREFY, CALEFY, and TUMEFY; six finish in S, including CHIEFS, BRIEFS, and GRIEFS. The remaining four split between T, A, and E: two end in T, one in A, and one in E.

Several Y endings share the -fy shape: RAREFY, CALEFY, CASEFY, and REDEFY. That visual family helps you test the final letter quickly, but do not assume the spellings are common; only 2 matches meet the frequency cutoff.

Which matches are worth checking in a tile game?

6-letter words with E as the 4th letter and F as the 5th letter offer a standout Scrabble score in HUMEFY: 17 points, followed by MADEFY at 15. CHIEFS, CASEFY, TEPEFY, TUMEFY, CALEFY, RUBEFY, and TABEFY each score 14, making several Y endings stronger plays than the recognizable plural.

Dictionary coverage is uneven: all 20 appear in Collins, compared with 11 in ENABLE and 12 in NWL2023. Fourteen have definitions, but dictionary presence does not make every form familiar. Check your game's word list before committing an unfamiliar play; Collins entries are not all accepted in every game.

One useful elimination rule follows from the endings: if the final square is not Y, S, T, A, or E, the pattern cannot fit. Starting letters are less diagnostic: T leads with 4, but C, G, and R each contribute 3.
