Word Origin & Etymology

Borrowed directly from Latin 'ergo' (meaning 'therefore' or 'consequently'), a contraction of the phrase 'e rego' ('out of a straight line' or 'in the right direction'). It gained widespread currency in English through Scholastic logic and René Descartes' famous philosophical dictum 'cogito, ergo sum' ('I think, therefore I am').
