Note

May contain character data mixed with any other elements defined in the dictionary tag set.

There is no consensus on the internal structure of etymologies, or even on whether such a structure is appropriate. The etym element accordingly simply contains prose, within which names of languages, cited words, or parts of words, glosses, and examples will typically be prominent. The tagging of such internal objects is optional.
