Et cetera (in English contexts pronounced /ɛtˈsɛtərə/) is a Latin expression that means "and other things", or "and so forth". Archaic abbreviations, most commonly used in legislation, notations for mathematics or qualifications, include &c., &/c., &e., &ct., and &ca.. Note that the ampersand is a ligature of "et".
