ascertain
Meaning: To find out or discover something with certainty through careful investigation or examination.
Ascertain is a formal synonym for 'find out' that implies thoroughness and definitiveness. It is a staple of legal, official, and investigative language, commonly appearing in police reports, audit findings, and regulatory correspondence. Unlike 'discover,' which may imply chance, ascertain suggests a deliberate effort to establish facts.
