Only two tournament-listed words fit this ending and length: AB and OB. They share their final B, split between A and O as opening letters, and tie at 4 points apiece. Collins recognizes both, while the ENABLE and NWL2023 totals are one each, so the dictionary choice matters as much as the clue.

At a glance: the two B-ending entries

  • AB and OB are the only two 2-letter words ending in B.
  • Both words score 4 points, so neither outranks the other on face value.
  • Their first letters split evenly: one begins with A and one with O.
  • Collins lists both; ENABLE and NWL2023 each list one.

Which 2-letter words end in B?

The complete pair is AB and OB. Each uses B as its final letter, but the opening tile differs: A gives you AB, while O gives you OB. That distinction matters when a rack or board fixes the first square; there is no third B-ending option at this length.

Both candidates score 4 points, so choosing between them is about fitting the available letters, not gaining a higher base score. If you have an A, AB is the match; with an O, OB is. Their equal scores make this a rare case where the board position, rather than the word's value, decides the play.

How do 2-letter words ending in B compare?

The B ending is unusually narrow: 17 two-letter words end in O, and 15 end in A, compared with just two ending in B. The opening letters also give this pair a tidy split, with one A-starting entry and one O-starting entry.

Dictionary coverage is the important limitation. Collins has both candidates, but ENABLE and NWL2023 each recognize only one of them. The aggregate counts do not identify which word appears in each smaller dictionary, so do not assume AB and OB are interchangeable across game versions; check the word list your game uses.

Questions people ask

Are AB and OB both accepted in every word game?
No, the two words do not appear in every dictionary. Collins includes AB and OB, while ENABLE and NWL2023 each include one of the pair. Which entry is accepted depends on the word list your game uses, so check that list before playing either word.
Which of AB and OB scores more?
Neither scores more: AB and OB are both worth 4 points. Their base scores tie, so the better fit depends on the letters available and the board position rather than a difference in their listed values.
Are there more 2-letter words ending in O than B?
Yes. There are 17 two-letter words ending in O, compared with just two ending in B. The O-ending group is much larger, while AB and OB are the complete pair for the B ending.
