Paleography is the deciphering of old texts. In Middle French manuscripts 3 letters cause difficulty. Abbreviation styles left over from Latin copying also need to be understood.
Scribes use different letter forms for three main letters in the early 1400s in French. The small letter r has differing forms which may look at first like the modern r, modern v and modern z.
Please take a look at the logo for this package at the top of the page. It is the words for 'The book' in French Le livre. Look carefully at the letter i, it has no real dot, although the scribe has drawn a faint stroke in the air.
Now look at the v, in Middle French the v and u are interchangeable and in this case the v looks more like a u to modern readers.
Now to the last 2 letters, can you see how there is no modern r-shape present at all? Ignore the three strokes of the iu-shape.
What is the letter before the -e?
