Pronunciation

Forms

slīm n or m (strong a-stem; genitive singular slīmes)[1]

Etymology

It is inherited from Proto-Germanic *slīmą (“slime”), from Proto-Indo-European *sley- (“smooth, slick, sticky”).[1] The noun is shared with Old Norse slím, Old Frisian slīm, Middle Low German slīm and Old High German slīm, and lives on in Dutch slijm and German Schleim.[2][3][4] Köbler gives the Old English noun as a neuter, Bosworth and Toller as masculine or neuter, and Orel leaves its gender open.[5][6][3]

Kroonen derives it from Proto-Indo-European *sleh₁i-mo-, a word confined to Europe, beside a form in ⟨*-no-⟩ in Proto-Slavic *slina (“saliva”), and compares Ancient Greek λείμαξ (leímax, “slug”) and Latin līmāx (“snail, slug”).[2] Orel adds Latin līmus (“mud, slime”) and Ancient Greek λειμών (leimṓn, “moist meadow”).[3] Holthausen and Köbler place it under the root Proto-Indo-European *slei- (“slimy, sticky; to glide”) (Pokorny 662), and Etymonline connects it with līm (“birdlime”).[7][5][8]

Earliest recorded meaning

The Dictionary of Old English Corpus has four instances of the word: three in glossaries and one in an anonymous homily.[9] In a glossary quoted by Bosworth and Toller it renders Latin limus “mud”, and elsewhere borbus and cena (for caenum) “mire, filth”.[6]

Semantic evolution

In Old English the word meant soft mud and mire as well as slime.[6][8] Clark Hall cites it from the Cambridge Psalter gloss and the glossaries.[10] It survived as Middle English slim, slyme, now slime.[1][8]
