6-letter words with S as the 1st letter and F as the 4th letter

A fourth-position F produces 55 matches, nine classed as common, and a high average tile score of 12.7. SUFFER, SELFIE, SULFUR, and SURFER are familiar options; SUFFIX leads the score table at 19. Final S and Y are the most frequent endings, but the list spans several more.

At a glance

• 55 matches fit, with nine classed as common.
• SUFFER, SELFIE, SULFUR, and SURFER are recognizable entries.
• SUFFIX scores 19, ahead of SUBFIX at 18.
• S ends 21 matches and Y ends 11.

Which everyday words fit the fixed F?

SUFFER, SELFIE, SULFUR, SURFER, and STIFLE make a solid first scan. The F sits fourth in each, but the preceding letters can make familiar patterns such as SELF- or SULF-. SHIFTS and SHAFTS show that an S-ending plural is common among the examples too.

There are 55 matches, while the related pattern with S first and R fourth has 248. That comparison shows how specifically the fixed F narrows the field. Nine matches fall in the common-word group, so use recognizable candidates first and regard specialist forms such as SEXFID or SPOFFY as dictionary-dependent rather than routine plays.

Does this set reward high-value letters?

SUFFIX is the top scorer at 19 points; SUBFIX follows at 18. SPIFFY, SEXFID, SKYFED, and SPOFFY reach 17. The average is 12.7, higher than many six-letter patterns, but the ceiling comes from unusual letter combinations rather than a guarantee that every candidate is familiar.

S is the final letter for 21 entries and Y for 11, followed by D at six. If your final tile is known, S and Y deserve the first checks. For the remaining endings, keep the fixed F in slot four as your anchor; do not assume every S-ending example is a plural unless the word itself supports that reading.
