A person who deliberately prevents others from understanding or knowing something, often by being vague or misleading.
The obscurantist avoided giving clear answers to the questions posed by the audience.
Obscurantist → It is formed from "obscurus" (meaning dark or obscure) and the suffix "-ist" (meaning one who practices or is concerned with). The term refers to someone who deliberately prevents the facts or full understanding of a subject, thus keeping it dark or obscure.
Think of someone who keeps things 'dark' or 'obscure' ('obscurus') and is a person who practices this ('-ist'). This helps you remember that an obscurantist is someone who obscures knowledge.
