passim

Passim is from the Latin word passus ("scattered"), itself from pandere, meaning "to spread." Pandere is the root of the common word expand and the not-so-common word repand, meaning "having a slightly undulating margin" (as in "a repand leaf" or "a repand colony of bacteria"). It is also the progenitor of pace, as in "keep up a steady pace." Passim itself appears in English both on its own and as part of the adverb sic passim, which means "so throughout." Sic passim is typically used to indicate that a word or idea is to be found at various places throughout a book or a writer's work.
