Sufficiently specialized lujvo or zi'evla with very specific definitions
will not need to be marked. I'm only proposing marking use of common words,
typically gismu, in a technical manner. Technically, when one does that,
they are sense-shifting it from a broad, laic term, to a more specialized,
technical one. Thus, marking it is desirable, so that it can be defined
within that particular technical field.
