fine: [12] Both the adjective and the noun fine have come a very long way since their beginnings in Latin finis ‘end’. The etymological sense of the adjective is ‘finished’ – hence, ‘of high quality’. It comes via Old French fin from Vulgar Latin *fīnus, an adjective formed from the Latin verb fīnīre ‘limit, complete’ (source of English finish). (A derivative of *finus was the noun *finitia, from which ultimately English gets finesse [15].) The noun fine also comes from an Old French fin, this time a noun descended directly from Latin fīnis.

In medieval times this was used for ‘money to be paid at the completion of legal proceedings’ – hence the present-day sense ‘payment imposed as a punishment’. From the same ultimate source, but reflecting different aspects of it, come confine [16] and define [14] (‘limitation’) and refine [16] (‘high quality’).
=> confine, define, final, finance, finesse, finish, refine

forum: [15] Originally Latin forum denoted an ‘out-of-doors place’ – it was related to forīs ‘outof- doors, outside’ and to forēs ‘door’, a distant cousin of English door. It came to be used for any outdoor open space or public place, and in particular for a market place (the most famous of which was the one in Rome, where public assemblies, tribunals, etc were held). Other English words from the same source are foreign, forest, and forensic ‘of legal proceedings’ [17] (from Latin forēnsis ‘of a forum as a place of public discussion’).

assize (n.)youdaoicibaDictYouDict
"session of a law court," c. 1300 (attested from mid-12c. in Anglo-Latin), from Old French assise "session, sitting of a court" (12c.), properly fem. past participle of asseoir "to cause to sit," from Latin assidere "to sit beside" (see assess). Originally "all legal proceedings of the nature of inquests or recognitions;" hence sessions held periodically in each county of England to administer civil and criminal justice.
inhibition (n.)youdaoicibaDictYouDict
late 14c., "formal prohibition; interdiction of legal proceedings by authority;" also, the document setting forth such a prohibition, from Old French inibicion and directly from Latin inhibitionem (nominative inhibitio) "a restraining," from past participle stem of inhibere "to hold in, hold back, keep back," from in- "in, on" (see in- (2)) + habere "to hold" (see habit (n.)). Psychological sense of "involuntary check on an expression of an impulse" is from 1876.
plea (n.)youdaoicibaDictYouDict
early 13c., "lawsuit," from Anglo-French plai (late 12c.), Old French plait "lawsuit, decision, decree" (9c.), from Medieval Latin placitum "lawsuit," in classical Latin, "opinion, decree," literally "that which pleases, thing which is agreed upon," properly neuter past participle of placere (see please). Sense development seems to be from "something pleasant," to "something that pleases both sides," to "something that has been decided." Meaning "a pleading, an agreement in a suit" is attested from late 14c. Plea-bargaining is first attested 1963. Common pleas (early 13c.) originally were legal proceedings over which the Crown did not claim exclusive jurisdiction (as distinct from pleas of the Crown); later "actions brought by one subject against another."
supersedeas (n.)youdaoicibaDictYouDict
writ to stay legal proceedings, Latin, literally "you shall desist," second person singular present subjunctive of supersedere "desist, refrain from, forebear" (see supersede).
