It's no use me denying facts, I'm henpecked, you can see!
'Twas on our wedding day my wife commenced to peck at me
The wedding breakfast over, I said, "We'll start off today
Upon our honeymoon."
Then she yelled, "What! waste time that way?"
[chorus] "Archibald, certainly not!
Get back to work at once, sir, like a shot.
When single you could waste time spooning
But lose work now for honeymooning!
Archibald, certainly not!"
[John L. St. John & Alfred Glover, "Archibald, Certainly Not"]
late 14c., artik, "of or pertaining to the north pole of the heavens," from Old French artique and directly from Medieval Latin articus, from Latin arcticus, from Greek arktikos "of the north," literally "of the (constellation) Bear," from arktos "bear;" also "Ursa Major; the region of the north," the Bear being the best-known northern circumpolar constellation.
This is from *rkto-, the usual Indo-European root for "bear" (source also of Avestan aresho, Armenian arj, Albanian ari, Latin ursus, Welsh arth). For speculation on why Germanic lost the word, see bear (n.). The -c- was restored from 1550s.
It is attested from early 15c. as "northern;" from 1660s as "cold, frigid." As a noun, with capital A-, "the northern polar regions," from 1560s.
1640s, "retention of what is old and obsolete," from Modern Latin archaismus, from Greek arkhaismos, from arkhaizein "to copy the ancients" (in language, etc.); see archaic. Meaning "that which is archaic," especially "an archaic word or expression," is by 1748.
"use of the bow and arrow," c. 1400, from Anglo-French archerye, Old French archerie, from archier "archer" (see archer).
"province over which an archbishop exercised authority," Middle English archebishop-riche, from Old English arcebiscoprice, from archbishop + rice "realm, dominion, province," from Proto-Germanic *rikja "rule" (from PIE root *reg- "move in a straight line," with derivatives meaning "to direct in a straight line," thus "to lead, rule").
