In standard Scrabble scoring, CO 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. CO 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.

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