prefix used to signify through, throughout, by,
for, or as an intensive as perhaps, by hap or
chance; perennial, that lasts throughout the year;
perforce, through or by force; perfoliate,
perforate; perspicuous, evident throughout or very

Originally, denoting that
the element to the name of which it is prefixed in the respective
compounds exercised its highest valence; now, only that the

thus, barium peroxide is the highest oxide of barium; while
nitrogen and manganese peroxides, so-called, are not the
highest oxides of those elements.
