late 14c., "to sing," from Old French chanter "to sing, celebrate" (12c.), from Latin cantare "to sing," originally frequentative of canere "sing" (which it replaced), from PIE root *kan- "to sing."
The frequentative quality of the word was no longer felt in Latin, and by the time French emerged the word had entirely displaced canere. Meaning "to sing as in the church service, in a style between song and recitation" is by 1580s. Related: Chanted; chanting.
"to celebrate May Day, to take part in May Day festivities," late 15c., from May. Maying as "the observance of May Day with all its sports and games" is attested from late 14c. (maiing).
And as a vapour, or a drop of raine
Once lost, can ne'r be found againe:
So when or you or I are made
A fable, song, or fleeting shade;
All love, all liking, all delight
Lies drown'd with us in endlesse night.
Then while time serves, and we are but decaying;
Come, my Corinna, come, let's goe a Maying.
[Robert Herrick, "Corinna's Going a-Maying," 1648]
Written as one word from mid-14c. As a verb, "to celebrate Christmas," from 1590s. Father Christmas is attested in a carol attributed to Richard Smart, Rector of Plymtree (Devon) from 1435-77. Christmas-tree in the modern sense is attested by 1835 in American English, rendering German Weihnachtsbaum. Christmas cards were first designed in 1843, popular by 1860s; the phrase Christmas-card was in use by 1850. Christmas present is from 1769. Christmas Eve is Middle English Cristenmesse Even (c. 1300).
also doggie, "a little dog, a pet word for a dog," 1825, from dog (n.) + -y (3). Doggy-bag "bag provided by restaurants for customers to take home leftovers" (presumably to feed to the dog) is attested by 1962.
LIVING IT UP. Marveling at size of sirloin steaks, Dave and Betty celebrate $4-a-week raise at a restaurant dinner. They paid $3.50 each, left with enough uneaten steak in a "doggie bag" to feed themselves, not the dog, all next day. [Life magazine, photo caption from article on living economically, April 6, 1962]
As an adj. doggy is attested from late 14c., from -y (2). The word has been used in various formations at least since late 19c. to describe the rear-entry variant of the human sex act when one partner is on all fours.
"stringed musical instrument, violin," late 14c., fedele, fydyll, fidel, earlier fithele, from Old English fiðele "fiddle," which is related to Old Norse fiðla, Middle Dutch vedele, Dutch vedel, Old High German fidula, German Fiedel "a fiddle;" all of uncertain origin.
The usual suggestion, based on resemblance in sound and sense, is that it is from Medieval Latin vitula "stringed instrument" (source of Old French viole, Italian viola), which perhaps is related to Latin vitularia "celebrate joyfully," from Vitula, Roman goddess of joy and victory, who probably, like her name, originated among the Sabines [Klein, Barnhart]. Unless the Medieval Latin word is from the Germanic ones.
FIDDLE, n. An instrument to tickle human ears by friction of a horse's tail on the entrails of a cat. [Ambrose Bierce, "The Cynic's Word Book," 1906]
Fiddle has been relegated to colloquial usage by its more proper cousin, violin, a process encouraged by phraseology such as fiddlesticks (1620s), contemptuous nonsense word fiddle-de-dee (1784), and fiddle-faddle. Century Dictionary  reports that fiddle "in popular use carries with it a suggestion of contempt and ridicule." Fit as a fiddle is from 1610s.
[sound a bell; emit a resonant sound] Old English hringan "cause (a bell) to sound;" also "announce or celebrate by the ringing of bells," from Proto-Germanic *khrengan (source also of Old Norse hringja, Swedish ringa, Middle Dutch ringen), probably of imitative origin. Related: Rang; rung.
Originally a weak verb, the strong inflection began in early Middle English by influence of sing, etc. The intransitive sense of "give a certain resonant sound when struck" is by c. 1200. Of places, "resound, re-echo," c. 1300. Of the ears or head, "have a continued buzz or hum in reaction to exposure to noise," by late 14c. In reference to a telephone, intransitive, by 1924; as "to call (someone) on a telephone by 1880, with up (adv.). The verb was much used in phrases of 20c. telephoning, such as ring off "hang up," ring back "return a call," ring in "report by telephone."
To ring down (or up) a theatrical curtain, "direct it to be let down" (or up) is by 1772, from the custom of signaling for it by ringing a bell; hence, in a general sense "bring to a conclusion." To ring up a purchase on a cash register is by 1937, from the bell that sounds in the machine. The specialized sense, especially in reference to coins, "give a resonant sound when struck as an indication of genuineness or purity," is by c. 1600, with transferred use (as in ring hollow) by 1610s. For ring a bell "awaken a memory," see bell (n.).
