1540s, "one who enters into a contract," from Late Latin contractor "one who makes a contract," agent noun from past-participle stem of Latin contrahere "to draw several objects together; draw in, shorten, lessen, abridge," metaphorically "make a bargain, make an agreement," from assimilated form of com "with, together" (see con-) + trahere "to draw" (see tract (n.1)).
From 1680s as "a muscle which contracts a part." Specifically "one who enters into a contract to provide work, services, or goods at a certain price or rate" is from 1724.
"pertaining to a tailor," 1807, from Modern Latin sartorius, from Late Latin sartor "tailor" (source also of French sartre "tailor"), literally "patcher, mender," from Latin sart-, past participle stem of sarcire "to patch, mend" (from PIE root *srko- "to make whole, make good"). The classical Latin word was sarcinator (fem. sarcinatrix).
Earlier in English in same sense was sartorian (1660s). Sartorius as the name of the long leg muscle (1704) is because it is used in crossing the legs to bring them into the position needed to sit like a tailor. Related: Sartorially.
before vowels phren-, word-forming element meaning "mind," also, in medical use, "diaphragm, muscle which parts the abdomen from the thorax;" from Greek phrēn, phrenos "the mind, spirit," also "the midriff, diaphragm," also (in plural, phrenes) "the parts around the heart, the breast," and hence "wits, sense, sanity, mind" on the notion of the breast or heart as the seat of thoughts and passions.
The word is of uncertain origin; Watkins has it under a proposed PIE root *gwhren- "to think." Beekes finds the connection with phrassein "to fence or hedge in" "semantically attractive," but there are phonetic difficulties, and he finds "quite feasible" a relationship with phrazomai "to think, consider" (later phrazein; see phrase (n.)), itself an isolated word.
late 14c., diafragma, in anatomy, "muscular membrane which separates the thorax from the abdominal cavity in mammals," from Late Latin diaphragma, from Greek diaphragma "partition, barrier, muscle which divides the thorax from the abdomen," from diaphrassein "to barricade," from dia "across" (see dia-) + phrassein "to fence or hedge in," which is of uncertain etymology. Beekes suggests it is a substrate word and finds "no convincing correspondence outside Greek."
The native word in the anatomical sense is midriff. From 1650s as "a partition" of any kind, "something which divides or separates;" 1660s in the special sense "thin piece of metal" serving some purpose (as a sound resonator, etc.). Meaning "contraceptive cap" is from 1933. Related: Diaphragmal; diaphragmatic.
c. 1300, corde, "a string or small rope composed of several strands twisted or woven together; bowstring, hangman's rope," from Old French corde "rope, string, twist, cord," from Latin chorda "string of a musical instrument, cat-gut," from Greek khorde "string, catgut, chord, cord," from PIE root *ghere- "intestine."
Also from c. 1300 as "string of a musical instrument." From c. 1400 as "a tendon or muscle." Figurative sense of "anything which binds or restrains" is from late 14c. Meaning "raised, cord-like rib on the surface of cloth" is from 1776. As a measure of wood of 128 cubic feet (eight feet long, four feet high and wide) first recorded 1610s, so called because it was measured with a cord of rope.
Clean Living is opposed to anything and everything which speaks for physical and mental disorder, dirt, disease, distress and discontent. Clean Living stands for babies, better born and better bred, better clothed and better fed; happier, healthier babies with normal play, normal environment and a normal chance to live and develop.

early 15c., "slanting, sloping, sideways; crooked, not straight or direct," originally of muscles or eyes, from Old French oblique (14c.) and directly from Latin obliquus "slanting, sidelong, indirect," which is perhaps from ob "against" (see ob-) + root of licinus "bent upward," from a PIE root meaning"to bend, be movable," the source of see limb (n.1). But De Vaan writes, "The etymology is unknown. Closest in form and meaning are līmus 'transverse' and sublīmis 'transverse from below upward', and the latter would be morphologically similar to oblīquus. Yet a root *lī- with different suffixes *-mo- and *-kwo- does not immediately make sense, and has no clear connections outside Italic."
Figurative sense of "indirect" is from early 15c. As a noun in anatomy in reference to a type of muscle the direction of whose fibers is oblique to the long axis of the body or to the long axis of the part acted, by 1838. Related: Obliquely; obliqueness.
