passim

The word 'passim' is a direct borrowing from Latin, where it functions as an adverb meaning "here and there, everywhere, at different places." It is derived from the Latin verb 'pandere,' meaning "to spread out," via its past participle stem 'pass-.' The semantic journey is straightforward: from the literal sense of spreading out or scattering, it came to denote something found scattered throughout a written work. Adopted into scholarly English in the 17th century, it serves as a concise, technical instruction in citations, indicating that a concept or reference appears frequently and in various locations within the cited source, rather than on a specific page.

This word is a Latin adverb adopted directly into English. It is not productively formed from separable English morphemes.
