The context, in which word is used, could change its meaning. This happens quite often and it's enough to look up a word in a dictionary to see a long list of diverse meanings that are specific to different contexts. For example, depending on the context, the phrase "What a jerk!" could mean a reference to an annoyingly stupid person or a bouncing, or thrusting motion. So the usage of a word outside of its common contextual understanding could bring about a major confusion.

A meaning of a technical term is also specific to a micro-social context.  Its usage within this context is a convention and therefore is being understood in a specific professional field in the framework of that convention.  Thus taking the term out of a micro-social context or bringing it into a wrong micro-social context introduces confusion and leads to miscommunication and unnecessary arguments.

An example of such phenomenon, in my view, is overlaying the term "Manual Therapy" over the micro-social semantic scope of Massage Therapy.
