Pronunciation
- /ˈmoː.nɑθ/[1]
Forms
mōnaþ m (strong consonant stem; genitive singular mōnaþes)[1] A consonant stem, with nominative plural mōnaþ beside mōnþas; otherwise it follows the a-stems.[2] In West Saxon the middle vowel is regularly syncopated only in this word, as in the genitive mōnþes.[3]
Etymology
It is inherited from Proto-West Germanic *mānōþ, from Proto-Germanic *mēnōþs (“month”).[1][4] The word is found in all the old Germanic languages: Gothic 𐌼𐌴𐌽𐍉𐌸𐍃 (mēnōþs), Old Norse mánaðr, Old Frisian mōnath, Old Saxon mānuth and Old High German mānōd.[4][5]
Kroonen derives it from Proto-Indo-European *meh₁n-ot-;[4][1] Wiktionary sees in it a derivative of *mḗh₁n̥s (“month, moon”), related to Proto-Germanic *mēnô (“moon”), the source of mōna.[4][1] Köbler traces the Indo-European word to the root *meh₁- (“to measure”).[5]
Earliest recorded meaning
The word is first recorded in the will of Abba the reeve (833×839), whose single sheet is held to be contemporary: a payment is to be made ymb twelf monað “every twelve months”.[6][7] The Vespasian Psalter gloss of the mid-ninth century renders Psalm 80 “Canite in initio mensis tuba” as Singað in fruman monðes horne “sing with the horn at the beginning of the month”.[8][7] A charter of the same years, held to be contemporary, sets a yearly render ymb .xii. monað “every twelve months”, and Oswulf's grant of 805×810, on a ninth-century sheet, asks for a commemoration ymb tuælfmonað “every twelvemonth”.[9][10]
Semantic evolution
The word names both the lunar and the calendar month: a computus text explains that the moon's month runs from new moon to new moon, twenty-nine days and twelve hours, and that the sun passes under one of the twelve signs each month.[11] In compounds it also meant “moon”: mōnaþsēoc is “lunatic”.[12][1] In the laws the plural stands after twelf and means a year.[13] The Old English names of the months are compounds of it.[14][1]
The word lived on as Middle English moneth, now English month.[15][1]
