Pronunciation

Forms

clamm m, also clomm; dative plural clammum, clommum.[2][3]

Etymology

It is inherited from Proto-Germanic *klam- (“to press together”), a noun from the Germanic root that also gave Old High German klamma (“cramp, fetter, narrow place”).[4][5] Holthausen compares Middle Low German klamme (“clamp, clasp”) and the adjective klamm (“narrow”).[5] Köbler connects it with the Old English verb clemman (“to squeeze”), from Proto-Germanic *klemmaną (“to squeeze, clamp”), and refers both to Proto-Indo-European *glem- (“lump, clamp”) (Pokorny 360).[2][6] Etymonline names the same root, or *glom- (“to hold, embrace”), as a possible source.[4]

Earliest recorded meaning

The word is first recorded in the poems of the late tenth-century codices.[7][8] In Andreas in the Vercelli Book the prisoners are on carcerne clommum fæste “fast in fetters in the prison”, and in the Exeter Book Christ the devil lies in carcerne clommum gefæstnad “held fast in fetters in the prison”.[7][8][9]

Semantic evolution

The word is mostly poetic: a band, bond or chain, and in a wider sense captivity, as in helle clommas “the bonds of hell” in Genesis.[10] In Beowulf it is the grip of a hand: Beowulf wished to bind Grendel heardan clammum “with hard grips”, and Grendel's mother seized him atolan clommum “in her terrible grasp”.[3][11][9] Prose uses it of the bonds of death and hell in the Blickling Homilies and Wulfstan, and a glossary renders Latin “clasma” with clam oððe wed “a pledge”.[12] It forms poetic compounds such as helleclom and wīteclom.[10]

Middle English clam meant a clamp or brace;[13][4] Etymonline thinks the name of the shellfish, English clam, is probably a use of that word.[13][4]

Usage notes

Wiktionary files the word under the page clam, beside clām “mud, clay”, a word of another origin;[1][16][12][5] Bosworth–Toller first treated both under one heading, and Toller's Supplement separates them.[1][16][12][5]
