simulcast

The word 'simulcast' is a modern portmanteau, coined in the mid-20th century with the advent of combined radio and television broadcasting. It ingeniously blends the Latin adverb 'simul', meaning "at the same time", with the English verb 'cast', which in broadcasting terminology means to transmit a signal. The term's logic is perfectly transparent: a "simultaneous broadcast". While 'simul' is a direct borrowing from Latin, 'cast' has a more complex journey, originating from a Scandinavian root meaning "to throw" and evolving in English to encompass the idea of projecting sound or pictures through the air. Thus, 'simulcast' literally and logically describes the act of throwing or transmitting content via multiple channels concurrently.

Structure: simul (same) + cast (broadcast) - simul: From Latin 'simul', meaning "at the same time, together". It functions as a combining form indicating simultaneity. - cast: From Old Norse 'kasta', meaning "to throw". In English, it developed the specific sense of transmitting sound or images via radio or television waves.
