Assuming something is true without proof, or being bold enough to do something that might be disrespectful.
From Latin 'praesumere' meaning 'to take beforehand,' from 'prae' (before) and 'sumere' (to take). Evolved to mean assuming or supposing without evidence.
The root literally means 'taking beforehand'—you grab the conclusion before you have the facts, which is why presuming is considered intellectually risky!
