Forms

agi m (genitive aga) (weak an-stem)[1]

Etymology

It is inherited from Proto-Germanic *agô,[1] a masculine n-stem made on the root of Proto-Germanic *agiz (“fear”);[2][1] Gersum notes that this stem type is found only in Scandinavia.[2][1] The Proto-Germanic noun was an s-stem from Proto-Indo-European *h₂egʰ-os, continued in Gothic 𐌰𐌲𐌹𐍃 (agis, “fear”) and Old English ege (“fear”); the extended Old High German agiso, Old Saxon egiso and egesa “terror” are formed from it.[3][4] Outside Germanic it is related to Ancient Greek ἄχος (ákhos, “pain, grief”) and Old Irish ad-ágor (“to fear”).[5][6] In Old Norse it belongs with aga, ógn, ótti, ýgr and ægir.[5][6]

Earliest recorded meaning

Menota's earliest record is aga in AM 619 4to, of 1200–1225.[7] ONP dates its first citation, from the Old Norwegian homilies, to 1212, in the sense “dread, awe”: Ða skelfr oll iorð fyrir aga mycclum “Then all the earth will tremble in great dread”.[8]

Semantic evolution

ONP gives the senses “dread, awe”, “(harsh) discipline” and “enmity, strife”.[8] The second is first dated in Ágrip, of 1225: Um daga fǫþor míns þá var lýþr undir aga miklom ok ótta “In my father's days the people lived under great constraint and fear”.[8] Fritzner and Baetke put “unrest, strife” first.[9][10] The King's Mirror has both “awe of God” and the discipline of youth, í œsku mæðan hann er undir aga “in youth, while he is under discipline”.[8][11] In skaldic verse it means strife and tumult, and once the raging sea.[12]

In Icelandic agi now means chiefly “discipline”, as does Danish ave.[11][13] It was borrowed into Middle English as aghe, the source of English awe.[2][14]
