language-shift logical tag?

Is there a logical tag to indicate that a word is in a different language?
What I mean is shown in an example:

What Godfrey did not know was that a shield is the <tag>sine qua non</tag>
of sparring. Thus, he died.

Or, if there is no tag specifically for this, what should I use? Cite? Em?
Suggestions, please. I'm on the list, so don't bother cc'ing. Thanks much.
