Pronunciation

  • /merʃ/, [merˠʃ][1]

Forms

mersċ m (strong a-stem; genitive singular mersċes, nominative plural mersċas)[1] Also written merisċ, and mærsc in a charter.[2]

Etymology

It is inherited from Proto-West Germanic *marisk (“marshy; marsh”), a formation in *-isk on Proto-Germanic *mari (“sea, lake”).[1] Köbler sets up a feminine *mariskō (“marsh, morass”) and refers the word to mere “lake, sea”.[3] The same formation is found in Old Frisian mersk, Old Saxon mersk and Old High German mersk.[3] Etymonline also derives it, with a “probably”, from the Proto-Germanic word for the sea.[4]

Kroonen explains the Proto-Germanic word for the sea as the regular continuation of a neuter i-stem Proto-Indo-European *móri (“sea”), the source also of Latin mare (“sea”) and Old Irish muir (“sea”).[5] Orel compares the same Latin and Irish words.[6]

Earliest recorded meaning

The word is first recorded in a charter of 858 by which King Æthelberht exchanged land at Mersham in Kent: the king made the land into folkland butan ðem merscum “except the marshes” and the salt-works at Faversham.[7] Its single sheet is of the mid-ninth century and is held by several scholars to be contemporary.[8]

Semantic evolution

The word names wet, low-lying ground: Bosworth and Toller quote the salt marsh of the psalms (on sealtne mersc, rendering “in salsuginem”), marshland that went with an estate in the charters, and the plants of the Old English Boethius whose home is on merscum “in marshes”.[2][9] In the glossaries it renders “calmetum”.[2] A legal text sets fersc “fresh water” against mersc.[10] As a name, Mersc is Romney Marsh in the Chronicle annal for 796.[2] In the charter bounds the word is one of the terms for marshland.[11]

It lived on as Middle English mersch and survives in English marsh.[4]
