Zsaz blink I was simplifying it slightly to be brief, but as a developmental linguist you can't not be aware that entirely different areas of the brain are used when swearing and listening to swearing.
This can be shown with modern medical equipment, but has been apparent even before such equipment became available. I am sure you have met many people who have lost the use of language after brain damage, and you must have come across the same subgroups that I have, those that lose all languag EXCEPT swear words, and those that lose swearwords but not other language.
these patterns of damage would not be so common if the two groups of words were stored in the same place.
I am also surprised you are not aware of the recent research into early language acquisition in children in which is has been shown that the brain picks up on statistically significant occurrences of the same string of sound and starts to pick these out of the whole flow of speech and recognise them as words. I have over the years heard so many parents and grandparents speak to babies in a baby way, with rhymming and repetition, "Oh look, a new toothy tooth" "Shall we have some dindins" "time for bye byes" etc, this has now been shown to be very beneficial, although most of us knew that intrinsically didn't we!
Same with tome and pitch of voice.
Anglo-saxon developed from English, then became pretty much obsolete, there is no classification of words considered "bad" because they come from anglosaxon - firstly no one classifies words as anglo saxon in their own head, secondly, as it came from English in the first place, there is no categoric way of identifying a word as anglosaxon.
I find your post a bit odd. I don't know what area of developmental language you are expert in, but not the areas I have up until now considered the areas of expertise of a developmental linguist. Some other kind I have not come across before maybe.
