I can think of two words that sound like the thing they describe: takeout and hybrid.
Takeout has such a literal meaning. Go to a restaurant and order for takeout. It sounds exactly what it means. Buy food and take it out somewhere to eat it. I can see images of those styrofoam containers when I think about the word takeout. The ones with a happy face and it said “Have a nice day” on it.
Hybrid also sounds like what it describe which means two different things that are joined together. When I hear or see that word, I think about hybrid cars like the Prius or that Lexus CT 200h hatchback. Sometimes when I look at something, like the ramen burger or the cronut, it just speaks hybrid to me.
So, yeah, these two words do sound like what they describe. Well, to me.
