"Easy to be held," hence "fit for a purpose." The silent h- was dropped in English and resisted academic attempts to restore it 16c.-17c. (see H), but some derivatives (such as habiliment, habilitate) acquired it via French. Able seaman, one able to do any sort of work required on a ship, may be the origin of this:

1835, a refashioning of anormal (1835) under influence of Latin abnormalis "deviating from a fixed rule, irregular," from ab- "off, away from" (see ab-) + norma "rule" (see norm).

The older form was from French anormal (13c.), from Medieval Latin anormalus, an altered (by association with norma) borrowing of Greek anomalos "uneven, irregular," from an-, privative prefix, "not" (see an- (1)) + homalos "even," from homos "same" (see same). Compare anomaly. "Few words show such a series of pseudo-etymological perversions." Another adjective was abnormous (1742) "irregular, misshapen," from Latin abnormis. Related: Abnormally.

1846, "an instance of abnormality, irregularity, deformity;" 1853 as "fact or quality of being abnormal," from abnormal (q.v.) + -ity.

aboard (adv., prep.) Look up aboard at Dictionary.com
late 14c., "at the side of a ship;" mid-15c., "onto or aboard a ship," probably in most cases from the Old French phrase à bord (compare Old French aborder "to board (a ship)"), from à "on" + bord "board," from Frankish *bord or a similar Germanic source (see board (n.2)). The word for the "boarding" or sides of a vessel being extended to the ship itself. The usual Middle English expression was within borde. The call all aboard! as a warning to passengers (on ships or railway cars) is attested from 1838 (compare French aller à bord "go aboard").
abode (n.) Look up abode at Dictionary.com
mid-13c., "action of waiting," verbal noun from abiden "to abide" (see abide). It is formally identical with the old, strong past participle of abide (Old English abad), but the modern conjugation is weak and abided is used. The present-to-preterite vowel change is consistent with an Old English class I strong verb (ride/rode, etc.). Meaning "habitual residence" is first attested 1570s.
aboil (adj.) Look up aboil at Dictionary.com
"boiling, on the boil," 1858, from a- + boil (v.).
abolish (v.) Look up abolish at Dictionary.com
"put an end to, do away with," mid-15c., from Old French aboliss-, present participle stem of abolir "to abolish" (15c.), from Latin abolere "destroy, efface, annihilate; cause to die out, retard the growth of," which is perhaps from ab- "from" (see ab-) + adolere "to grow," from PIE *ol-eye-, causative of root *al- (3) "to grow, nourish" (see old), and perhaps formed as an antonym to adolere.

But the Latin word rather could be from a root in common with Greek ollymi, apollymi "destroy." Tucker writes that there has been a confusion of forms in Latin, based on similar roots, one meaning "to grow," the other "to destroy." Now generally used of institutions, customs, etc.; application to persons and concrete objects has long been obsolete. Related: Abolished; abolishing.
Abolish is a strong word, and signifies a complete removal, generally but not always by a summary act. It is the word specially used in connection with things that have been long established or deeply rooted, as an institution or a custom : as to abolish slavery or polygamy. [Century Dictionary, 1900]

1520s, "act of abolishing; state of being abolished," from Middle French abolition or directly from Latin abolitionem (nominative abolitio) "an abolition, an annulling," noun of action from past participle stem of abolere "destroy" (see abolish). Related: Abolitionary ("destructive"); abolitional ("pertaining to abolition").

Specific application to "opposition to the trans-Atlantic African slave trade" as a political question is first attested 1788. By 1823 abolition was being used in regard to proposals or arguments to end American slavery itself, and after 1832 this was the usual sense of the word until the effort was accomplished by the 13th Amendment (1865). The alternative noun abolishment (1540s) seems not to have acquired a special use in reference to slavery issues.

In a general sense, abolisher has been used at least since 1742.
abominable (adj.) Look up abominable at Dictionary.com
mid-14c., "exciting disgust or loathing, morally detestable," from Old French abominable (12c.) and directly from Late Latin abominabilis "deserving abhorrence," from stem of Latin abominari "deplore (as an evil omen)," hence, generally, "detest, execrate, deprecate" (see abomination).

The more common Middle English form was abhominable, which persisted into 17c.; it is a folk-etymology, as if from Latin ab homine "away from man" (thus "beastly"). In early Modern English sometimes misdivided as a bominable. Related: Abominably; abominableness. Abominable snowman (1921) translates Tibetan meetaoh kangmi.

early 14c., "abominable thing or action;" late 14c., "feeling of disgust, hatred, loathing," from Old French abominacion "abomination, horror, repugnance, disgust" (13c.), from Latin abominationem (nominative abominatio) "abomination," noun of action from past participle stem of abominari "shun as an ill omen," from ab- "off, away from" (see ab-) + omin-, stem of omen (see omen).

In biblical use, often "that which is ceremonially impure." The meaning was intensified by folk etymology derivation from Latin ab homine "away from man" (thus "beastly"); Wyclif and Chaucer both have abhominacioun, and abhominable was mocked by Shakespeare in "Love's Labour's Lost."
aboriginal (adj.) Look up aboriginal at Dictionary.com
1660s, "first, earliest, existing from the beginning," especially in reference to inhabitants of lands colonized by Europeans, from aborigines (see aborigine) + -al (1).

Related: Aboriginally; aboriginality; aboriginalism.
aborigine (n.) Look up aborigine at Dictionary.com
1858, mistaken singular of aborigines (1540s; aboriginal is considered the correct singular in English), from Latin aborigines "the first inhabitants," especially of Latium, hence "the first ancestors of the Romans;" possibly a tribal name, or from or made to conform to the Latin phrase ab origine, which means literally "from the beginning," from ab "from" (see ab-) + ablative of origo (see from origin). Extended 1789 to natives of other countries which Europeans have colonized. Australian slang shortening Abo attested from 1922 (n.), 1906 (adj.).
aborning (adv.) Look up aborning at Dictionary.com
"while being born," 1893, American English; see a- (1) + born + -ing (2).
abort (v.) Look up abort at Dictionary.com
1570s, "to miscarry in giving birth," from Latin abortus, past participle of aboriri "to miscarry, fail, disappear," a compound word used in Latin for deaths, miscarriages, sunsets, etc., which according to OED is from ab-, here as "amiss" (see ab-), + stem of oriri "appear, be born, arise," from PIE root *ergh- "to mount" (see orchestra). Watkins, however, derives the second element from a suffixed form of PIE root *er- (1) "move, set in motion."

From 1610s as "to deliberately terminate" anything, but especially a pregnancy. Intransitive use in aeronautics and space-flight is by 1946. Transitive meaning "to cause (a woman) to miscarry" is recorded from 1933; with the fetus or pregnancy as the object of the action by 1974. Related: Aborted; aborting. The Latin verb for "produce an abortion" was abigo, literally "to drive away."
abortifacient (n.) Look up abortifacient at Dictionary.com
1875, noun ("that which causes miscarriage") and adjective ("producing abortion"), from Latin abortus (see abort) + facientem "making," related to facere "to make, do" (see factitious). An earlier noun for this was abortive (1640s), also a special use of an adjective.
abortion (n.) Look up abortion at Dictionary.com
1540s, "the expulsion of the fetus before it is viable," originally of deliberate as well as unintended miscarriages; from Latin abortionem (nominative abortio) "miscarriage; abortion, procuring of an untimely birth," noun of action from past participle stem of aboriri "to miscarry" (see abort).

Meaning "product of an untimely birth" is from 1630s; earlier in this sense was abortive (early 14c.). Another earlier noun in English for "miscarriage" was abort (early 15c.). In the Middle English translation of Guy de Chauliac's "Grande Chirurgie" (early 15c.) Latin aborsum is used for "stillbirth, forced abortion." Abortment is attested from c. 1600; aborsement from 1530s, both archaic. Aborticide (1875) is illogical. Compare miscarriage.

In 19c. some effort was made to distinguish abortion "expulsion of the fetus between 6 weeks and 6 months" from miscarriage (the same within 6 weeks of conception) and premature labor (delivery after 6 months but before due time). The deliberate miscarriage was criminal abortion. This broke down late 19c. as abortion came to be used principally for intentional miscarriages, probably via phrases such as procure an abortion.
Criminal abortion is premeditated or intentional abortion procured, at any of pregnancy, by artificial means, and solely for the purpose of preventing the birth of a living child : feticide. At common law the criminality depended on the abortion being caused after quickening. [Century Dictionary, 1899]
Foeticide (n.) appears 1823 as a forensic medical term for deliberate premature fatal expulsion of the fetus; also compare prolicide. Another 19c. medical term for it was embryoctony, with second element from a Latinized form of Greek kteinein "to destroy." Abortion was a taboo word for much of early 20c., disguised in print as criminal operation (U.S.) or illegal operation (U.K.), and replaced by miscarriage in film versions of novels. Abortium "hospital specializing in abortions," is from 1934, in a Soviet Union context.
abortionist (n.) Look up abortionist at Dictionary.com

abortive (adj.) Look up abortive at Dictionary.com
late 14c., "born prematurely or dead," from Latin abortivus "prematurely born; pertaining to miscarriage; causing abortion," from abort-, past participle stem of aboriri "disappear, miscarry, fail" (see abort). From 14c.-18c. stillborn children or domestic animals were said to be abortive. Transferred meaning "not brought to completion or successful issue" is from 1590s. Also see abortion. Related: Abortiveness.
abound (v.) Look up abound at Dictionary.com
"be in great plenty," early 14c., from Old French abonder "to abound, be abundant, come together in great numbers" (12c.), from Latin abundare "overflow, run over," from Latin ab- "off" (see ab-) + undare "rise in a wave," from unda "a wave," from PIE *unda-, nasalized form of root *wed- (1) "water, wet" (see water (n.1)). Related: Abounded; abounding; abounder "one who has plenty or is wealthy" (1755).

English seems to always have used in the -ou- spelling, though in Middle English an excrescent h- sometimes was added. The vowel in Old French abonder, abondance is a continuation of a Merovingian Latin scribal use of -o- for classical Latin -u- to attempt to identify a sound that had evolved since classical times. In French eventually this sound came to be represented by -ou-. Compare French tour "tower," from Old French tor, from Latin turris; court (n.), from Old French cort, from Latin curtus; French outre from Latin ultra, etc. However -o- remained before a nasal (as nombre from numerus, monde from mundum, etc.).

about (adv., prep.) Look up about at Dictionary.com
Middle English aboute, from Old English abutan (adv., prep.), earlier onbutan "on the outside of; around the circumference of, enveloping; in the vicinity of, near; hither and thither, from place to place," also "with a rotating or spinning motion," in late Old English "near in time, number, degree, etc., approximately;" a compound or contraction of on (see on; also see a- (1)) + be "by" (see by) + utan "outside," from ut (see out (adv.)).

By c. 1300 it had developed senses of "around, in a circular course, round and round; on every side, so as to surround; in every direction;" also "engaged in" (Wist ye not that I must be about my Father's business?), and gradually it forced out Old English ymbe, ymbutan (see ambi-) in the sense "round about, in the neighborhood of."

From mid-13c. as "in the matter, in connection with." From early 14c. as "in partial rotation, so as to face in a different direction." From late 14c. as "near at hand, about one's person." "In a circuitous course," hence "on the move" (late 13c.), and in Middle English "be about to do, be busy in preparation for," hence its use as a future participle in (to be) about to "in readiness, intending." Abouts (late 14c.), with adverbial genitive, still found in hereabouts, etc., probably is a northern dialectal form.

To bring about "cause or affect" and to come about "happen" are from late 14c. About face as a military command (short for right about face) is first attested 1861, American English.
above (adv., prep.) Look up above at Dictionary.com
Middle English above, aboven (also aboun in northern dialects, abow in southwestern dialects), from Old English abufan (adv., prep.), earlier onbufan "above, in or to a higher place, on the upper side; directly over, in or to a higher place than," a contraction or compound of on (also see a- (1)) + bufan "over."

The second element is itself a compound of be "by" (see by) + ufan "over/high" (from Proto-Germanic *ufan-, source also of Old Saxon, Old High German oban, German oben; from PIE root *upo; see up (adv.)).

From c. 1200 as "of higher rank or position, superior in authority or power; of higher rank than, superior to." This sense in Middle English perhaps was reinforced by a literal use of above in the sense "higher at the table than," thus "in a place of greater honor than, taking precedence over" (mid-14c.) From mid-14c. as "in addition to;" also "superior to, out of reach of, not condescending to." From late 14c. as "more" (in number, linear measurement, weight, value); "older; better than, more desirable than, superior to."

Phrase above all "before other considerations" is from late 14c. To be above (someone's) head in the figurative sense "out of range of his or her intellect" is from 1914 (above in the sense "not to be grasped or understood by" is from mid-14c.). In Middle English to be above erthe was "above ground, unburied," hence "living, among the living."

Abraham Look up Abraham at Dictionary.com
masc. proper name, name of the first of the Patriarchs in the Old Testament, from Hebrew Abraham "father of a multitude," from abh "father" + *raham (cognate with Arabic ruham "multitude"); the name he altered from Abram "high father," from second element ram "high, exalted." Related: Abrahamic; Abrahamite.

Abraham-man was an old term for mendicant lunatics, or, more commonly, frauds who wandered England shamming madness so as to collect alms (1560s). According to the old explanation of the name (at least from 1640s), they originally were from Bethlehem Hospital, where in early times there was an Abraham ward or room for such persons, but the ward might have been named for the beggars.
