In formal writing and academia, to posit often implies reasoned assumption. Philosophers posit principles to build ethical systems. Scientists posit hypotheses to test with data. There is an air of disciplined tentativeness.
In informal conversation, you might hear someone say ‘Let’s posit’ as a more elevated way of saying ‘suppose’ or ‘imagine.’ It sounds a bit more deliberate than ‘assume’ or ‘say.’

Common Misconceptions About meaning of posit
One common mistake is treating posit as synonymous with assert in the strongest sense. Positing is not always a full-throated claim. Often it is provisional, a move toward exploration rather than a conclusion. If you posit a model, you may still be open to counterevidence.
Another error is thinking posit is archaic or overly formal. True, it reads as formal, but it is active in contemporary academic writing, journalism, and public debates. It signals intentionality: someone is placing an idea to be worked on.
Related Words and Phrases
Posit sits near verbs like assume, propose, put forward, positon? No, not that last one. Think propose, postulate, hypothesize, and posit’s sibling ‘postulate.’ Each has shades of meaning. Postulate often implies foundational necessity. Hypothesize leans toward testability. Propose is more general and social.
