Like people have defined what a chair is, and what "wet" is and what "blue" is, so they have defined "good" and "bad" and "evil" and "awesome" and "flying" and "love" and "friend" and "hate" and "information" and "knowledge" and "experience" and "look" and all the myriad words in every conceivable dictionary.
G. E. Moore argues that you cannot define good (like you can a chair)...
...we cannot define "good" by explaining it in other words. We can only point to an action or a thing and say "That is good." Similarly, we cannot describe to a blind person exactly what yellow is. We can only show a sighted person a piece of yellow paper or a yellow scrap of cloth and say "That is yellow."

Nor is the dictionary:

56 different cases of the application of "good"... damn!!
Yellow is a color. Colors are electromagnetic waves of different wavelengths, in the visible part of the e.m. spectrum.
Sounds are waves of different wavelengths in the audible air-pressure wave spectrum. Higher frequencies equate to what we call higher pitch in sound.... at some point, the frequency becomes so high that our ears can't pick it up. We call that ultra-sound. The same happens for low frequencies. Lower the pitch and there is a frequency below which most humans can't hear... and you get infra-sound.
For light, it's similar. Higher frequencies have been called the blue or purple
part of the spectrum. Lower frequencies have been called the red part of the spectrum. Right after the red, comes yellow, then green, then blue and purple.
Purple is similar to violet... violet is the highest frequency most humans can see.... beyond it, lies ultra-violet.
Red is the lowest frequency humans can see... below it, we have infra-red.
I guess I can explain... but it doesn't do it justice... at least to our eyes.
