7-letter words with O as the 1st letter and F as the 3rd letter

This frame often creates a doubled F at the start: OFFICER, OFFICES, OFFLINE and OFFSIDE are easy checks. The pattern is not limited to OFF-, though; OXFORDS and OFFRAMP show other useful shapes. Seven matches are common, and OFFPEAK leads the score list at 19.

At a glance for O-1st and F-3rd

• Thirty seven-letter words match O first and F third.
• OFFICER, OFFICES and OFFLINE show the repeated-F shape.
• S is the most frequent final letter, with 11 matches.
• OFFPEAK scores 19; OXFORDS follows at 18.

The doubled-F cluster has exceptions

OFFENSE, OFFENCE, OFFENDS, OFFSETS and OFFHAND continue the familiar OFF- run. OXFORDS is a clear counterexample to assuming the second letter must be F, and OFFRAMP also shifts the shape after the fixed positions.

Eleven words end in S; six end in E. OFFPEAK scores 19, just above OXFORDS at 18.

A rack-search tip

A small list for exact-position solving

Thirty matches make this a compact clue set, with an average score of 14.3. Seven entries are common by frequency, so OFFICER, OFFERED and OFFICES are easier recognition points than the full set.

The fixed F can sit after another F, as in OFFICER, or after X, as in OXFORDS. That distinction quickly separates a broad positional clue from a simple OFF- prefix search. Beyond the S and E endings, three words each close in D, R or T, such as OFFERED, OFFICER and OFFBEAT.

OFFPEAK is the scorer to retain for a board with room for all seven tiles. OXFORDS offers another high value, while familiar OFFICES is easier to recognize during a fast solve. Dictionary coverage splits the list: all 30 words are in Collins, 21 in NWL2023, and 19 in ENABLE, so verify rarer entries such as OFFCAST before a North American game.
