"horizontal piece of wood in a cricket wicket," c. 1742, originally "a cross bar" of any sort (1570s), probably identical with Middle French bail "horizontal piece of wood affixed on two stakes," and with English bail "palisade wall, outer wall of a castle" (see bailey).

bail (v.1) Look up bail at Dictionary.com
"to dip water out of," 1610s, from baile (n.) "small wooden bucket" (mid-14c.), from nautical Old French baille "bucket, pail," from Medieval Latin *baiula (aquae), literally "porter of water," from Latin baiulare "to bear a burden" (see bail (n.1)).

To bail out "leave suddenly" (intransitive) is recorded from 1930, originally of airplane pilots. Perhaps there is some influence from bail (v.2) "procure (someone's) release from prison." Related: Bailed; bailing.

bail (n.1) Look up bail at Dictionary.com
"bond money, security given to obtain the release of a prisoner," late 15c., a sense that apparently developed from that of "temporary release from jail" (into the custody of another, who gives security), recorded from early 15c. That evolved from earlier meaning "captivity, custody" (early 14c.). From Old French baillier "to control, to guard, deliver" (12c.), from Latin baiulare "to bear a burden," from baiulus "porter, carrier," which is of uncertain origin; perhaps a borrowing from Germanic and cognate with the root of English pack, or perhaps from Celtic. De Vaan writes that, in either case, "PIE origin seems unlikely." In late 18c. criminal slang, to give leg bail meant "to run away."
bailey (n.) Look up bailey at Dictionary.com
early 14c., baylle, "wall enclosing an outer court" of a castle, etc. (c. 1200 in Anglo-Latin), a variant of bail, from Old French bail "stake, palisade, brace," which is of unknown origin, perhaps ultimately connected to Latin bacula "sticks," on notion of "stakes, palisade fence."

The word was later extended to mean the outer court itself. Hence Old Bailey, seat of Central Criminal Court in London, so called because it stood within the ancient bailey of the city wall. The surname Bailey usually is from Old French bailli, a later form of baillif (see bailiff).

These dealers [hucksters] ... on purchasing their bread from the bakers, were privileged by law to receive thirteen batches for twelve, and this would seem to have been the extent of their profits. Hence the expression, still in use, "A baker's dozen." [H.T. Riley, "Liber Albus," 1859]
But Brewer says the custom originated when there were heavy penalties for short weight, bakers giving the extra bread to secure themselves.

The British troops suffered from the cold in the Crimean War, and the usage might be a remembrance of that conflict.

bald (adj.) Look up bald at Dictionary.com
c. 1300, ballede, "wanting hair in some part where it naturally grows," of uncertain origin. Perhaps with Middle English -ede adjectival suffix, from Celtic bal "white patch, blaze" especially on the head of a horse or other animal (from PIE root *bhel- (1) "to shine, flash, gleam;" see bleach (v.)).

But connection with ball (n.1), on notion of "smooth, round" also has been suggested, and if not formed from it it was early associated with it.

The b- (instead of -p-) for ph- substitution shows it entered Latin through a third language (Klein suggests Illyrian).
baleful (adj.) Look up baleful at Dictionary.com
Old English bealufull "dire, wicked, cruel," with -ful + bealu "harm, injury, ruin, evil, mischief, wickedness, a noxious thing," from Proto-Germanic *balwom (source also of Old Saxon balu, Old Frisian balu "evil," Old High German balo "destruction," Old Norse bol, Gothic balwjan "to torment"), from PIE root *bhelu- "to harm."
