Inndyr

Inndyr is a Norwegian word (primarily Bokmål) that can function as both a verb and a noun, although its usage as a noun is far less common.

As a verb, inndyr means to convince oneself (or others) of something, often something that is not necessarily true or substantiated by evidence. It implies a degree of self-deception or wishful thinking. It can also suggest persuasion through repeated or forceful assertions. The subject actively participates in accepting the idea, even if it lacks a solid foundation. The act of 'inndyr' can be deliberate or subconscious.

As a noun (though rarely used), inndyr can refer to the act of convincing oneself or the resulting belief, often carrying a connotation of delusion or unfounded conviction.
