Etymology
The word 'emission' originates from the Latin verb 'emittere', meaning 'to send out'. This verb is itself a compound of the prefix 'e-' (a variant of 'ex-', meaning 'out') and the verb 'mittere' (meaning 'to send, let go, throw'). The noun form 'emissio' was derived to denote the action or process of sending out. Over time, the meaning evolved from the general act of dispatching to the specific modern sense of discharging substances like light, particles, or gases from a source.
