And just in case you wanted to know the etymology of the word fart is quite interesting:
It cannot but come as a surprise that against the background of countless important words whose origin has never been discovered some totally insignificant verbs and nouns have been traced successfully and convincingly to the very beginning of Indo-European.Â FartÂ (ânot in delicate useâ) looks like a product of our time, but it has existed since time immemorial. Even the nuances have not been lost: one thing is to break wind loudly (farting); quite a different thing is to do it quietly (the now obscure âfistingâ). (This fist has nothing to do withÂ fistÂ âclenched fingersâ and consequently isnât related toÂ fisting, a sexual activity requiring, as we are warned, great caution and a lot of tender experience. This reminds me of the instruction Sergei Prokofiev gave to his First Piano Concerto: âCol pugno,â that is âwith a fistâ.)
Both words for the emission of wind (fartÂ andÂ fist) were current in the Old Germanic languages.Â FrataÂ andÂ fĂsaÂ (the accent over the vowel designates its length, not stress) turned up even in Old Icelandic mythological poems. According to a popular tale, the great god Thor was duped by a giant and spent a night in a mitten, which he took for a house. He was so frightened, as his adversary put it, that he dared neither sneeze nor âfist.â In another poem, the goddess Freyja, notorious for her amatory escapades, was found in bed with her brother and farted (apparently shocked by the discovery).
The words were as vulgar then as they are today. Yet even grammar proves their antiquity. Some verbs (they are called strong) form their principal parts by changing the root vowel, for instance,Â write/wrote/written,Â sing/sang/sung. Others (they are called weak) add a dental suffix (dÂ orÂ t) in the preterit and the past participle, for example,Â beg/begged/begged,look/looked/looked,Â wait/waited/waited.Â Strong verbs belong to the most ancient part of the Germanic vocabulary.Â FartÂ was one of them; however, it occurred in several forms. Modern German has retainedÂ farzenÂ (now a weak verb, thoughÂ furzenÂ is the most common form) andÂ FurzÂ (a noun). In the older period, German also hadÂ furzenÂ andÂ ferzan. Engl.Â fartÂ goes back toÂ ferten, an exact congener ofÂ ferzan. Although it was recorded only in the verbal nounÂ ferting, its existence can be taken for granted. I assume that the groupÂ erÂ in it changed toÂ arÂ in the same way in whichÂ personÂ yielded its doubletÂ parsonÂ andÂ clerkÂ becameÂ Clark(in British English,Â clerkÂ andÂ ClarkÂ are homophones).
