1520s, "that which is the matter of something, material substance," from Modern Latin materialitas, from materialis "of or belonging to matter," from Latin materia "matter, stuff" (see matter (n.)). From 1560s as "state or quality of being material;" 1640s as "quality of being important to matters at hand, essentiality."
mid-14c., "real, ordinary; earthly, drawn from the material world" (contrasted with spiritual, mental, supernatural), a term in scholastic philosophy and theology, from Old French material, materiel (14c.) and directly from Late Latin materialis (adj.) "of or belonging to matter," from Latin materia "matter, stuff, wood, timber" (see matter (n.)).
From late 14c. as "made of matter, having material existence; material, physical, substantial." From late 15c. as "important, relevant, necessary, pertaining to the matter or subject;" in the law of evidence, "of legal significance to the cause" (1580s).
late 14c., "hinder, impede the movement of," originally by fastening a block of wood to something, from clog (n.). Meaning "choke up with extraneous matter" is 1670s; intransitive sense "become choked up with extraneous matter" is from 1755. Related: Clogged; clogging.
a word used in philosophy and metaphysics of systems of thought which deduce all phenomena from a single principle (1832); also "the doctrine that only one being exists" (1862), from German Monism (by 1818) or directly from Modern Latin monismus, from Greek monos "alone" (from PIE root *men- (4) "small, isolated"); also see -ism. First used in German by German philosopher Baron Christian von Wolff (1679-1754), who applied it to those who deny the substantiality either of mind or matter. Fowler defines it as "any view of that makes the universe consist of mind with matter as a form of mind, or of matter with mind as a form of matter, or of a substance that in every part of it is neither mind nor matter but both," and writes that it is a contrast to dualism.
