7-letter words with B as the 3rd letter and O as the 4th letter

The fixed middle letters narrow the search, but the words around them vary widely: ONBOARD starts with O, while REBOUND starts with R. Only four matches rank among the commonest English words, so many entries are specialist vocabulary or inflections. The list combines words accepted by at least one tournament dictionary; check your game's word list before playing an unfamiliar entry.

7-letter words with B third and O fourth: at a glance

• There are 110 matches across the tournament dictionaries.
• ENABLE accepts 81; Collins accepts 104, and NWL2023 accepts 88.
• U, E, and R are the most common first letters, with 16, 15, and 14 words.
• S ends 43 matches; D is next with 22.
• EMBOXED tops the scores at 19 points.

Which letters begin and end these words?

U leads the starting-letter group with 16 words, just ahead of E at 15 and R at 14. Examples show how different those openings can be: UNBOUND and INBOUND share an ending, while REBOUND gives the pattern a familiar everyday face.

S and D dominate the final position, together accounting for 65 matches. That makes plural forms and past-tense forms worth checking when your rack or crossing letters point to an S or D; LABOURS, REBOOTS, and ELBOWED are examples. ONBOARD and CABOOSE show that other endings remain possible.

Which matches score highest?

EMBOXED leads at 19 points, while KABOCHA, KOBOCHA, REBOZOS, and EMBOXES each score 18. UNBOXED follows at 17. These are strong candidates when a premium letter square can boost a valuable tile, but the fixed B and O do not guarantee an easy play.

The contrast between score and familiarity is striking: only four of the 110 matches are common, yet ONBOARD, ROBOTIC, REBOUND, and INBOUND are recognisable options. For 7-letter words with B third and O fourth, start with those familiar examples when solving; switch to less common entries such as EMBOXED or KABOCHA when the board or remaining letters demand them.
