obscurantism

The word's journey begins with the Latin adjective obscurus, meaning 'covered, dark, hidden', which itself may derive from the Proto-Indo-European root skeu-, meaning 'to cover, conceal'. In the 18th century, this root combined with the Latin-derived adjectival suffix -ant to form 'obscurant', describing a person or thing that obscures. The final layer, the Greek-derived nominal suffix -ism, was added to create an abstract noun denoting the systematic practice or policy of preventing enlightenment. Thus, the literal logic of 'making things dark' evolved into the modern abstract concept of deliberately withholding knowledge to maintain power or social control.

Structure: obscur (dark) + ant (adjective suffix) + ism (doctrine or practice) - obscur: From Latin obscurus, meaning 'dark, dim, hidden'. Functions as the core root conveying the sense of darkness or concealment. - ant: A suffix of Latin origin (-ant-), forming adjectives meaning 'performing (a specified action)' or 'being in a (specified) state'. Here, it forms the adjective 'obscurant'. - ism: A suffix of Greek origin (-ismos), forming nouns denoting a distinctive practice, system, or philosophy, often one based on the preceding stem.
