If we were to examine Sars' question in its literal context ... "Is SWEARING part of the English Language?" ... then what would the correct answer be? Whether we like to admit to it or not, I daresay there are very few [if any!] Brits who haven't, at some point in their lives, sworn - uttering the odd "oath" or - (and I'm certainly no exception!).

Going back to when I was at school ... from 1949 to 1961 ... I seem to recall none of the Etymological English Dictionaries - with which we were issued - ever containing words that were then considered rude. (Not that it stopped us using them - for sheer devilment if nothing else!). But times changed radically over the intervening decades since ... so that nowadays virtually all reputable dictionaries define words that leave practically nothing to the imagination. And rightly so! And while I'm not condoning the toleration of *foul language to the extent where nowadays every second word that trips off the tongue appears to be a swear word, *its use (in a modified sense) can prove beneficial - even therapeutic - in appropriate circumstances, e.g. as an outlet for extreme anger or frustration.
