The word "transmission" is built upon the Latin verb mittere, meaning "to send, let go, throw." The prefix trans-, meaning "across," was added to create the compound transmittere, which literally meant "to send across." This concept of sending something across a distance or barrier is the core idea. The noun form "transmission" was subsequently formed in English by adding the suffix -ion, which denotes an action or process. Thus, the etymological logic moves from the literal act of "sending across" to encompass the modern abstract meanings of transferring energy, signals, or information from a source to a receiver, whether through mechanical systems, electronic waves, or communicative acts.

Structure: trans (across) + miss (send) + ion (noun suffix) - trans: Latin origin, a prefix meaning "across," "beyond," or "through." - miss: Latin origin, from the root of the verb mittere, meaning "to send." - ion: Latin origin, a suffix forming nouns denoting action or condition.
