What does exec mean?
"Exec" is an informal abbreviation of "executive," used to describe a person who holds a senior managerial or leadership position within a company or organization. It appears frequently in business journalism, casual workplace conversation, and headlines, where brevity matters — phrases such as "top exec" and "chief exec" are staples of financial reporting. The term carries a slightly breezy, insider tone compared with the more formal "executive," making it well suited to informal speech but less appropriate for official documents or academic prose. Its plural is "execs." Beyond the corporate sense, "exec" also has a specialized meaning in computing, where it names a command or system call that launches another program, particularly in Unix-like operating systems. Derived ultimately from the Latin verb "exsequi," meaning to follow out or carry through, the word connects to a broader family including "execute" and "execution," reflecting the underlying idea of carrying plans into action at the highest levels of an organization.
