6-letter words with F as the 3rd letter and O as the 5th letter

This pattern leaves just two open slots, but its matches range from familiar terms such as TEFLON to less familiar forms such as REFFOS. All 14 appear in Collins; eight also appear in NWL2023, and seven in ENABLE. None fall among the most common English words, so an obscure match may not be accepted where you play.

What stands out in this letter pattern

• There are 14 matches, and none rank among the most common English words.
• UPFLOW, BOFFOS, BUFFOS, and BIFFOS each score 14 points.
• Four words end in S, four end in W, and three end in L.
• Four matches start with B; R is next with three.
• INFLow and REFLOW are familiar flow-related examples among the matches.

How do these six-letter words differ?

The fixed F and O leave the first, second, fourth, and final positions to vary. That produces a notably small group: the pattern with N in the third position and O in the fifth has 143 matches, compared with 14 here. A narrow letter constraint can therefore cut a broad search sharply.

The endings split evenly between S and W, while L appears three times. REFFOS, BOFFOS, and BIFFOS show the S ending; INFLOW, REFLOW, and ONFLOW show the W ending. If your clue fixes the final letter too, start with that split rather than scanning every entry.

Which matches score best?

UPFLOW, BOFFOS, BUFFOS, and BIFFOS share the highest listed base score at 14 points. Their double F supplies much of that value, so the best fit depends on your board: a high-value letter on a premium square can matter more than choosing a longer-looking word.

INFLow and REFLOW score 12 points each, while BEFOOL and MUFLON score 11. The less familiar top scorers are a real limitation for casual play; verify acceptance in your chosen game's dictionary instead of assuming every tournament list matches.
