fem. proper name, from Latin (Maria) Magdalena, "Mary of Magdala," the companion and supporter of Jesus, from Greek Magdalene, literally "woman of Magdala," from Aramaic (Semitic) Maghdela, place on the Sea of Galilee, literally "tower" (compare Hebrew migdal "tower," from gadal "be great or high"). The vernacular form of the name, via French, has come to English as maudlin.
"reformed prostitute," 1690s, in reference to "Mary called Magdalene out of whom went seven devils," disciple of Christ (Luke viii.2), who often is identified (especially since 5c. and especially in the Western Church) with the unnamed penitent "woman in the city, which was a sinner" in Luke vii.37-50. See Magdalene.
c. 1600, "tearful, weeping" (a sense now obsolete), from Middle English fem. proper name Maudelen (early 14c.), from Magdalene (Old French Madelaine), woman's name, who in the Middle Ages was believed to be identical with the repentant sinner forgiven by Jesus in Luke vii.37 (see Magdalene). Thus in paintings, she often was shown weeping as a sign of repentance. Meaning "characterized by tearful sentimentality, over-emotional" is recorded by 1630s. Also in old slang "tipsy, foolish from drink" (by 1700), from maudlin-drunk (1610s) "in the sentimental and tearful stage of intoxication."
"person having red hair," mid-13c. (1256 as a surname), from red (adj.1) + head (n.). Red (adj.), of persons, "having red hair" is from late Old English. Both Cain and Judas formerly were reputed to have had red or reddish-yellow beards.
The Carrot pate be sure you hate, for she'l be true to no man,
But put her too 't and she will do 't, and oft turns very common:
She that is red upon the head will doubtless ne'r forsake it,
But wanton be, assuredly, and willingly will take it.
["The True Lover's Admonition," Roxburghe Ballads, c. 1680]
Traditional ideas about red-haired people are not complimentary. Physically, they are said to sweat easily, bleed copiously, have a strong foxy smell, and such bad breath that they can raise blisters on other people simply by breathing over them. Morally, they are expected to be 'bad children' who cause nothing but trouble; they will be hot-tempered, treacherous, and highly sexed. The medieval notion that Judas, Cain, and Mary Magdalene were red-heads arose from these beliefs, and helped to perpetuate them. ["Oxford Dictionary of English Folklore," 2000]
As an adjective, "having red hair," from 1660s. Red-headed is attested from 1660s; red-haired from c. 1500.
early 12c. as an adjective, seinte, "holy, divinely inspired, worthy of worship," used before proper names (Sainte Marian Magdalene, etc.), from Old French saint, seinte "holy, pious, devout," from Latin sanctus "holy, consecrated," past participle of sancire "consecrate" (see sacred). It displaced or altered Old Englishsanct, which is directly from Latin sanctus.
From an adjective prefixed to the name of a canonized person, it came to be used in English by c. 1200 as a noun, "a specific canonized Christian," also "one of the elect, a member of the body of Christ, one consecrated or set apart to the service of God," also in an Old Testament sense "a pre-Christian prophet."
It is attested by late 13c. as "moral or virtuous person, one who is pure or upright in heart and life."
The adjectives also were used as nouns in Late Latin and Old French: "a saint; a holy relic." The Latin word also is the source of Spanish santo, santa, Italian san, etc., and also ultimately the source of the word in most Germanic languages (Old Frisian sankt, Dutch sint, German Sanct).
Perhaps you have imagined that this humility in the saints is a pious illusion at which God smiles. That is a most dangerous error. It is theoretically dangerous, because it makes you identify a virtue (i.e., a perfection) with an illusion (i.e., an imperfection), which must be nonsense. It is practically dangerous because it encourages a man to mistake his first insights into his own corruption for the first beginnings of a halo round his own silly head. No, depend upon it; when the saints say that they—even they—are vile, they are recording truth with scientific accuracy. [C.S. Lewis, "The Problem of Pain," 1940]
