7-letter words with F as the 3rd letter and I as the 4th letter

F and I together in positions three and four create a wide family of words, including OFFICER, DEFICIT, DEFINED, and REFINED. The ending distribution is less even: 26 finish in S and 17 in D. HAFIZES, a less familiar entry, is the top scorer at 22.

F third and I fourth at a glance

• 70 words fit the F-third, I-fourth frame.
• OFFICER, DEFICIT, and REFINED are recognizable matches.
• HAFIZES scores 22; AFFIXED scores 21.
• S ends 26 words and D ends 17.
• R is the most common first letter, with 14 matches.

Why do so many words end in S or D?

S closes 26 matches and D closes 17, far ahead of T at 7. OFFICES, AFFIRMS, and AFFIXES illustrate the S ending; DEFINED and REFINED show the D group. That split suggests checking suffix-like endings after you have placed the fixed F and I.

R is the most frequent starting letter, with 14 words, followed by A at 10 and D and I at 9 each. REFINED and REFILLS make the R opening familiar, while AFFIXED starts with A. Seven matches are common-frequency, so recognizable examples form a useful core but not the whole set.

The placement clue works best when you check the two neighboring positions as one unit.

Can an unusual word beat AFFIXED?
