7-letter words with O as the 1st letter and B as the 2nd letter

The O-B opening leads to a compact set with a sharp split between everyday vocabulary and specialist entries. Just 8 of the 53 words count as common by frequency, while 48 have definitions. Collins lists all 53; NWL2023 includes 40 and ENABLE includes 39.

The O-B pattern at a glance

• There are 53 seven-letter entries beginning OB, including OBVIOUS, OBJECTS, and OBSERVE.
• Only 8 entries are common by frequency; OBSCURE and OBELISK are recognizable, but many others are rarer.
• The most frequent final letter is S: 21 words end that way, including OBJECTS and OBLIGES.
• The two top Scrabble scorers are OBLOQUY and OBSEQUY, tied at 21 points.
• Collins accepts all 53 entries, NWL2023 accepts 40 and ENABLE accepts 39.

What makes this O-B pattern distinctive?

The endings are concentrated: S appears 21 times, while E is next with 11. D and Y each finish 5 entries, and the remaining endings occur only three times or fewer. That makes a known final S a strong narrowing clue.

The familiar words cluster around the opening: OBVIOUS, OBJECTS, OBSERVE, OBSCURE, and OBESITY are all examples. The frequency contrast matters, though: common vocabulary accounts for only 8 entries, so an unfamiliar candidate is not automatically a miss.

Dictionary coverage differs by game. Collins accepts all 53 entries, compared with 40 in NWL2023 and 39 in ENABLE; check your game's word list before relying on a less familiar answer.

Which O-B words score highest in Scrabble?

OBLOQUY and OBSEQUY share the top score at 21 points each. Both are less familiar than OBJECTS, which scores 18, so the best scoring play may be a word you rarely see.

OBLIQUE and OBELIZE also reach 18 points, while OBJURED scores 17. The gap between the top pair and these next scorers is small; board placement can matter more than choosing a rare entry purely for its face value.

For 7-letter words with O as the 1st letter and B as the 2nd letter, the practical limitation is vocabulary: only 8 are common. Keep OBVIOUS and OBSERVE in mind as familiar candidates, and treat high-scoring OBLOQUY as a specialist option.
