Which prefix conveys the meaning of "with or together"?

The prefix "co" conveys the meaning of "with" or "together." This prefix is derived from Latin and is commonly used in words that indicate partnership or collaboration, such as "cooperate" (to work together) and "coauthor" (a person who writes with another). By using "co," it signifies that the actions or entities mentioned are joined or connected in some way.

In contrast, the other prefixes do not carry this meaning. The prefix "anti" typically means "against," while "dis" conveys a sense of negation or reversal, such as in "disagree" (not in agreement). The prefix "pre" means "before" and is used in words like "preview" (to view something before). Therefore, "co" is the only prefix among the options that accurately represents the idea of being "with" or "together."
