co scrabble

The word "co" is not a valid Scrabble word. It is considered an abbreviation (for example, company, carbon monoxide, Colorado) and abbreviations are generally not allowed in Scrabble. Therefore, "co" cannot be played in official Scrabble games according to major dictionaries like the Official Scrabble Players Dictionary (OSPD) and NASPA Word List (NWL). However, there are other playable two-letter words starting with "c" such as "ch" in some international word lists like Collins Scrabble Words (CSW), but not in the common US/Canada dictionaries. In summary, "co" is not allowed in Scrabble play.
