What is the sociological difference between the words 'common' and normal'?

Thanks for your own explanation...... good.

To me, common means ordinary and normal means usual. The difference between ordinary and usual can perhaps be better understood through their antonyms...... extraordinary and unusual...... common isn't necessarily desirable whereas normal is mostly desirable.

Yay, stirring up some controversy. That's the hip-hop way. Lol Just kidding. Umm technically speaking, there's a two-letter difference. But seriously, think about this. A black guy goes up to his white friend and says, "What's up my n*gga?". The white guy responds, "Chillin". What you're saying is that the black guy said the white guy was a n*gger...(and that's incorrect) So in a way, the word has evolved past it's slang version of the word n*gger and has now been used as a noun for a person, regardless of race. There will always be people who don't like the word being used but it's been proliferated to the point that you can't do much about it. And just remember this, I didn't change the meaning of the word, society did. How many songs(particularly rap songs) have used the word?

The vast majority of people are of average height and this is normal.

A small portion of people are unusually short or tall, but this is common.

A tiny fraction of people are extremely short or tall, but this is rare.

Normal is what every individual and society believes himself/herself/itself to be.

Common is what every individual believes himself/herself not to be.
