The Origin of Disassociate or Dissociate

The word dissociate comes from the Latin word dissociare, which means to separate or divide.

It entered English hundreds of years ago and became the standard spelling in dictionaries and formal writing.

Later, many English speakers naturally formed the word disassociate because it resembles other words beginning with dis-, such as:

• Disagree
• Disconnect
• Disapprove
• Disappear

Over time, disassociate became accepted by major dictionaries, although many language experts still recommend dissociate because it reflects the original Latin spelling.

Today, both spellings are considered correct.
