把東西攪在一起的機器
最接近字面的一家：做混合的那台機器，而混什麼由前面的名詞決定。
noun · B1
A machine or piece of equipment that mixes things together: food in a bowl, cement on a building site, or hot and cold water behind a tap or a shower.
攪拌機、混合器
核心畫面
Put -er on mix and you get the one that does the mixing — and English never says who or what that is. So the word can land on a machine with blunt blades turning in a bowl, on a slow drum of cement on a building site, on a tap that brings hot and cold water into one flow, on a desk of sliders holding four sound sources in balance, on the bottle of tonic that goes into another drink, on the person who moves round a room joining strangers up, and even on the evening that was arranged so that joining up would happen. The picture to hold is simply: things were separate, and this is what brings them together. Everything around the word — the noun in front of it, the room you are standing in — tells you which separate things are meant.

「mixer」可以想成 mix 加上 -er：做混合的那一個。英文沒有說那一個是誰，也沒有說混的是什麼。所以它可以落在碗裡轉的鈍葉片上，也可以落在工地那個慢慢轉的水泥桶上。可以是把冷熱水併成一道的水龍頭。可以是一整排推桿、把四軌聲音壓平的機器。可以是倒進另一杯裡的那瓶通寧水。也可以是那個在場子裡走動、把陌生人接起來的人。甚至可以是為了讓大家認識而辦的那個晚上。要記住的畫面很簡單：本來是分開的，而這個東西讓它們合在一起。至於合的是什麼，就看它前面的名詞，以及你人站在哪裡。From the word’s history
Mixer is mix plus -er, the agent ending that goes back through Middle English -ere to Old English -ere: the one that does it. The ending names a doer without saying whether the doer is a person, a machine, or an ingredient, which is why one word covers all of them.
「mixer」就是 mix 加上 -er。-er 這個字尾一路從古英語 -ere 傳下來，意思是「做這件事的那一個」。它不規定那一個是人、是機器，還是被加進去的材料。這正是為什麼同一個字可以蓋住這麼多東西。
