Repetition of words

[Jorge_Stolfi]

Not all of them:

Well, ahem, aham, I would say that the first example was originally Chee, but the ligature of the Ch faded almost to invisibility (you can still see a very faint trace of it), so much so that it was missed by the Retracer.

As for the second example, it could indeed be ee + ee.  Or it could be a little more extreme case of the above, where the original ligature of the Ch has, by now, faded to complete invisibility...

(And I am quite sure that the second example was fully retraced, because the plume of the r is not a quick and tapering counterclockwise swirl of the pen, but a slow and broad clockwise (re)tracing of it.)

All the best, --jorge
