OB (noun): the branch of medicine dealing with childbirth and care of the mother. Additional senses: a major river of western Siberia; flows generally northward and westward to the Gulf of Ob and the Kara Sea.

In standard Scrabble scoring, OB totals 4 points before multipliers. That sum uses official letter values: common tiles (A, E, I, O, U, L, N, S, T, R) are worth 1, while D and G are 2, B, C, M, P are 3, F, H, V, W, Y are 4, K is 5, J and X are 8, and Q and Z are 10. OB relies mostly on common tiles, which often makes it easier to play from a mixed rack but caps the raw ceiling compared with high-premium words.

OB is 2 letters long, begins with O, ends with B, and sorts to the alphagram BO. There is 1 anagram in this dictionary sharing that exact letter bag. Letter makeup: 1 vowel, 1 consonant.

Among 18 tracked 2-letter entries, OB ranks by raw score (4 points). Anagram alternatives include BO — useful when you need the same tiles with a different hook letter. Similar-length words in the same dictionary include XX, FZ, HQ, QH; open their word pages to compare endings, vowel weight, and crossover potential.

Strategically, OB carries 1 vowel and 1 consonant. Its vowel-heavy shape often plays cleanly from racks with excess vowels. Hooks on O or B are common study angles; browse words starting with O and words ending with B to rehearse parallel sets.

OB is a 2-letter answer slot candidate. Filter by length 2, starts with O, ends with B, or contains letters from your crossing entries in the Crossword Solver and Pattern Finder.
