On pg 340 of Gauss' Disquisitiones Arithmeticae (chapter 235) is the phrase "et quae inde sequantur euoluemus". What does this word "euoluemus" mean? I couldn't find it in the online dictionaries.
A more modern way to spell that would be ēvolvēmus: "we will unfold" the things that may follow from there. The form you're most likely to find in a dictionary is ēvolvō.
It's only recently that it's become common to distinguish the vowel u from the consonant v, and many editions still don't distinguish i from j, or long ē from short e.
