The left hemisphere is typically a segmental (Language) processor. The right hemisphere is a gestalt processor.
Show me someone who is swearing and I will show you someone who is mad, surprised, scared, happy, in love, in pain, (excluding Tourettes Syndrome) -- all emotional states.
It is a combinative communication. If I hit my thumb with a hammer, it doesn‰t feel like I have communicated if I say, "Oh green grass!." Hence, changing the combination of sounds does change the meaning.
Here is further evidence why I say swearing is not language. It is pretty well known now that for most individuals, the left cerebral hemisphere of the brain is a segmental processor.
Hence, it carries the burden of language acquisition and use.
The right hemisphere is a gestalt processor, which ingests information in whole units. This includes such things as memories of pictures, maps and even songs.
