After reading the chapter on concept-formation, I was curious as to how new words are formed. I notice I use some onamatopoeic language . . . words that aren’t actually words but sound like they might be, especially words that sound like the thing they describe.
Can you give an example of what you mean? “Onomatopoeia” is generally used to refer to a word whose sound is similar to that of the thing it denotes. Reasonably clear examples would be “woof”, “meow”, “hiss”. Even though such words may well have historically originated from imitation of sounds, they are conventionalized in the particular language. If you don’t know that language, your ability to guess the referent won’t be very high. Anyhow, I can’t imagine what words that aren’t actual words you might be using (you see the contradiction, I assume), or how they relate especially to optional concepts.
I’ve heard that the same idea can “sound” different to people that speak different languages; is this accurate?
The concepts “cow”, “water” and “sky” are represented by very different words across languages, which sound quite different. I assume that this is almost self-evident, and that your question is really more narrowly about imitative words. Generally this is true, but there are some broad tendencies, for example using the vowel “ee” for small things and “oo” for big things, which is based on resonance properties of the vowel sounds and the fact that large resonators have a low resonance frequency like “oo” does, and small resonators have a high resonance frequency like “ee” does.
Essentially, I’m curious as to how people pick words to represent concepts.
This, on the other hand, is a very different question. You learn the correct existing word-unit relationship from others who already know the words (“cow”, “torque” and so on). When you invent a word to go with some concept (because you’ve invented some nifty new tool and you need a name for it), you have to make a choice. Although the label you assign to a product is technically arbitrary, the best policy for successful product naming is to construct a name that is sufficiently similar to existing words that you’d want people to think of (e.g. “Glatulence” is not a good name for a perfume), but not so close that you’ll end up in court (I don’t care if your name is “Mike Row”, do not name your fabric softener “Mike Row Soft”). Name-inventing is a business.
