Pronunciation

Etymology

It is borrowed from Latin iūdiciārius (“of a court of justice”), perhaps through French judiciaire,[2][3][4] from iūdicium (“judgment, court of justice”),[2][3] from iūdex (“a judge”) (see judge).[3] An earlier use borrowed directly from Latin, in a Wycliffite text of before 1415, did not survive.[2]

Earliest recorded meaning

Forming a judgement, discerning, especially in astrology: 1604 in Barnhart and the OED.[2][5] Relating to the courts or the administration of justice is from 1611.[2][5]

Semantic evolution

The noun, the body of judges or the judicial branch of government, is from 1788 in Etymonline;[3] judicature had been used in this sense from the 1590s.[3] Merriam-Webster dates a noun sense to 1623.[4]
