Post-

undefined:

Post- is a prefix describing a member in a system who was originally an introject, or had a source, but no longer feels connected to it.

Related Terms
A headmate such as this may be called a post-fictive or post-factive.

If the disconnection was due to trauma, this may be synonymous to distive.

The prefix Pre- is the opposite, as it describes a member that was not originally an introject and gained a source later on.

Etymology
Post means "after" in Latin.
