It's "And" with a capital "A" !
Your "s" is clearly(?) the same as the "d" in "and"
Your "u" could just as easily be an "n" - these are notoriously easy to confuse.
Your "et" is one letter, "A" - the second "etus" is actually clearer that the "et" is one letter.
It doesn't help that they omit punctuation, does it?
