Entries linking to jus
jurist n.
mid-15c., "one who practices law;" 1620s, "a legal writer, one who professes the science of the law," from Old French juriste (14c.), from Medieval Latin iurista "jurist," from Latin ius (genitive iuris) "a right," especially "legal right or authority, law," also "place where justice is administered, court of justice," from Old Latin ious, perhaps literally "sacred formula," a word peculiar to Latin (not general Italic) that originated in the religious cults, from PIE root *yewes- "law" (compare Latin iurare "to pronounce a ritual formula," Vedic yos "health," Avestan yaoz-da- "make ritually pure," Irish huisse "just"). Related: Juristic. The more mundane Latin law-word lex meant specific laws as opposed to the body of laws.
The Germanic root represented by Old English æ "custom, law," Old High German ewa, German Ehe "marriage," sometimes is associated with this group, or it is traced to PIE *ei- "to go."
juice n.
c. 1300, jus, juis, jouis, "liquid obtained by boiling herbs," from Old French jus "juice, sap, liquid" (13c.), from Latin ius "broth, sauce, juice, soup," from PIE root *yeue- "to blend, mix food" (cognates: Sanskrit yus- "broth," Greek zymē "a leaven," Old Church Slavonic jucha "broth, soup," Lithuanian jūšė "fish soup"). Meaning "the watery part of fruits or vegetables" is from early 14c. Meaning "liquor" is from 1828; that of "electricity" is first recorded 1896.
