Etymology

It is inherited from Middle English filth, earlier fulthe,[2][3][4] inherited from Old English fȳlþ (“uncleanness, foulness; rotting matter”),[5][6][3][7][8] inherited from Proto-West Germanic *fūliþu,[1] a noun formed from the Germanic base of foul with the suffix -th.[9][6][7][10] Merriam-Webster derives it from fūl (“foul”),[11] and Etymonline calls it a classic case of i-mutation.[7] It is cognate with Old Dutch fūlitha (“decay, moral corruption”),[9] Old Saxon fūlitha (“decay, foulness”),[9][6][7] Middle Low German vǖlede (“decay, dirt”),[9] Dutch vuilte[6][7][8] and Old High German fūlida (“stench, decay, depravity”),[9][6][12] the source of Middle High German vūlde.[9][12] Köbler reconstructs it as Proto-Germanic *fūliþō (“rottenness”).[12]

Earliest recorded meaning

Decay or decayed matter within the body, later pus or another unclean body fluid: in Old English, first in the West Saxon Gospels (Matthew 23);[9][6] the sense "dirt, unclean matter" is also Old English, in glosses on Aldhelm.[9]

Semantic evolution

The moral sense, corruption or impurity, is as old as the physical ones: Ælfric already used it in his Lives of Saints.[9] In Middle English filth covered anything foul or defiling, from mud, refuse and ordure to rust on metal, impurities and vermin;[3] Chaucer used it 19 times, of filth and of moral foulness.[13] The old sense "rotting or purulent matter" died out in the late 17th century, though the OED has stray examples up to 1903.[10][9] Foul or obscene language is recorded from before 1400,[9] and since before 1375 the word has been a term of abuse for a vile person;[9] in the 16th and 17th centuries it was used of a prostitute.[14][11] In English dialect, from Cumberland to Cornwall, a filth was a scoundrel or rascal,[15][11] and in the American South Appalachians and the English south-west Midlands it meant weeds and underbrush (from 1834).[9][11] Sexually explicit material has been called filth since 1872,[9] and British slang has called the police the filth since 1967.[9][16] In Cheshire and Cornwall the dialect word filth meant a fill or sufficiency, and Wright compares fulth.[15]
