Etymology

It is inherited from Proto-West Germanic *fūl (“foul, dirty”), from Proto-Germanic *fūlaz.[1][2] The adjective is found across Germanic: Gothic 𐍆𐌿𐌻𐍃 (fūls, “foul, putrid”), Old Norse fúll, Old Frisian fūl and Old High German fūl, with Dutch vuil and German faul in the modern languages.[3][2][4]

Kroonen explains it as a stem in *-lo- built on the root Proto-Indo-European *puH- (“to rot”), the root of Lithuanian pṹliai (“pus”).[3] Orel derives it from the verb behind Old Norse fúinn (“rotten”) and also points to the Lithuanian word.[2] Holthausen and Köbler put it with the same root, which has Latin pūs (“pus”) and pūteō (“to stink”) in Latin.[5][4]

Earliest recorded meaning

The first dated record is in the Pastoral Care (Hatton 20, 890×897), where a ruler must keep himself clean so that he can wipe from other men's hearts ðæt ðæron fules sie, “whatever is foul in them”.[6][7]

Semantic evolution

The word covers physical dirt and decay, as in fūl wīn glossing Latin “spurcum vinum”, and moral foulness, as in þurh fūle synne “through foul sin” in Christ.[8] In one riddle of the Exeter Book the speaker is wyrslicre ðonne þes wudu fula, “viler than this rotten wood”.[8][1] In the laws it is used of a person found guilty: gif se mynetere ful wurþe, “if the moneyer is found guilty”.[8][9] Used as a noun, fūl means foulness and impurity, and in the laws a crime or guilt.[10][9] It glosses Latin “foedus”, “olidus” and “putidus”.[4]

It lived on as Middle English foul “dirty, filthy”, now English foul;[11] the sense "ugly", rare in Old English, became frequent in Middle English.[12]
