1706, originally a contraction of am not, and considered proper as such until in early 19c. it began to be also a generic contraction of are not, is not, has not, etc. This was popularized in representations of London cockney dialect in Dickens, etc., which led to the word being banished entirely from correct English. Bartlett ("Dictionary of Americanisms," 1848) reports that hain't for "have not" is "A contraction much used in common conversation in New England."ETD ain't.2

air (n.1)

It is possibly from a PIE *awer- and thus related to aeirein "to raise" and arteria "windpipe, artery" (see aorta) on notion of "lifting, suspended, that which rises," but this has phonetic difficulties.ETD air (n.1).2

In Homer mostly "thick air, mist;" later "air" as one of the four elements. Words for "air" in Indo-European languages tend to be associated with wind, brightness, sky.

But some French sources connect this Old French word with the source of air (n.1), and it also is possible these senses in English developed from or were influenced by air (n.1); compare sense development of atmosphere and Latin spiritus "breath, breeze," also "high spirit, pride," and the extended senses of anima.ETD air (n.2).3

"translucent, whitish, marble-like mineral used for vases, ornaments, and busts," late 14c., from Old French alabastre (12c., Modern French albâtre), from Latin alabaster "colored rock used to make boxes and vessels for unguents," from later Greek alabastros (earlier albastos) "vase for perfumes," probably a foreign word, perhaps from Egyptian 'a-labaste "vessel of the goddess Bast."

Perhaps so called in reference to trees growing nearby (compare Alamogordo, New Mexico, literally "big poplar," and Spanish alameda "a shaded public walk with a row of trees on each side"); but the popular name seems to date from the period 1803-13, when the old mission building was the base for a Spanish cavalry company from the Mexican town of Alamo de Parras in Nueva Vizcaya.ETD Alamo.3

Alaric

Visigothic masc. proper name, literally "all-ruler," from Proto-Germanic *ala- "all" (see all) + *rikja "rule" (from PIE root *reg- "move in a straight line," with derivatives meaning "to direct in a straight line," thus "to lead, rule").ETD Alaric.2

late 14c., "a call to arms in the face of danger or an enemy," from Old French alarme (14c.), from Italian all'arme "to arms!" (literally "to the arms"); this is a contraction of phrase alle arme.ETD alarm (n.).2

Alle is itself a contraction of a "to" (from Latin ad; see ad-) + le, from Latin illas, fem. accusative plural of ille "the" (see le); with arme, from Latin arma "weapons" (including armor), literally "tools, implements (of war)," from PIE root *ar- "to fit together."ETD alarm (n.).3

The interjection came to be used as the word for the call or warning (compare alert). It was extended 16c. to "any sound to warn of danger or to arouse," and to the device that gives it. From mid-15c. as "a state of fearful surprise;" the weakened sense of "apprehension, unease" is from 1833. The variant alarum (mid-15c.) is due to the rolling -r- in the vocalized form. Sometimes in early years it was Englished as all-arm. Alarm clock is attested from 1690s (as A Larum clock).ETD alarm (n.).4
