One way to picture transmitter: the sending end. Something starts here, leaves, and arrives somewhere else, and this is the thing that pushed it out. At the far end sits the receiver, the catching end. Whether what travels is a radio signal, a virus, or a way of speaking that a grandmother hands to a child, the picture does not change: this end lets it go, and another end takes it in.
From the word’s history
The packet records transmitter as transmit plus the suffix -er. That -er covers both a person who does something and a thing that does it, which is why one word holds both a machine and a person who passes something on.
詞源資料把這個字記成 transmit 加上字尾 -er。而 -er 既能指「做這件事的人」，也能指「做這件事的東西」。這正好說明為什麼同一個字可以一邊是山上的發射台，一邊是把疾病或文化傳給別人的人。
