Did you know?

Dissociate and its synonymous sibling disassociate can each mean "to separate from association or union with another." Both trace back to the Latin verb sociare, meaning "to join," which comes in turn from socius, a noun meaning "companion." (Socius is associated with many English words, including social and society.) Dis- in this case means "do the opposite of," so both dissociate and disassociate indicate severing that which is united. Some argue that disassociate is illogical because it indicates separating and uniting simultaneously. Dissociate is also preferred by some because it is shorter (and by a grand total of two letters) but both words are in current good use.
