单词	alum
释义	alumal‧um /ˈæləm/ noun [countable] American English informal Word Origin WORD ORIGINalum Origin: 1300-1400 Old French, Latin alumen Examples EXAMPLES FROM THE CORPUS He learned, among other things, what alum served for, besides dyeing. He sprayed a picric acid and alum solution into the noses of forty-six hundred Alabamians, to no good end. Here he also made alum and sulphuric acid by the lead chamber process. Much of the long-distance trade was in commodities connected with the cloth industry, notably dyestuffs such as woad and alum. Spence's product was an ammonium alum which gradually displaced the potash alum which had been made principally at Whitby. The treatment so far had been innocuous: quinine pills and injections of alum water. Whit- or white-leather was leather that had been dressed with alum, and it was often horse-leather. word sets WORD SETS► College AA, nounacademia, nounacademic, adjectiveacademic, nounacademy, nounalum, nounalumna, nounalumni, nounalumnus, nounassistant professor, nounAssociate of Arts, nounassociate professor, nounaudit, verbBA, nounbachelor's degree, nounBig Man on Campus, nounblue book, nounbrother, nounBSc, nounbursar, nounbursary, nouncampus, nounCantab, chair, nounchancellery, nounchancellor, nounclass, nouncoed, nouncommencement, nouncommunity college, nounconservatoire, nounconservatory, nounconvocation, nouncourse, nouncredit, nouncum laude, adverbdean, noundean's list, noundiploma, noundissertation, noundoctor, noundoctoral, adjectivedoctorate, nounDoctor of Philosophy, noundon, noundorm, noundormitory, noundouble first, noundown, adverbelective, nounexaminer, nounextension, nounextramural, adjectivefaculty, nounfinancial aid, nounfirst class, noungrad, noungrad school, noungraduate, noungraduate, verbgraduate, adjectivegraduate school, noungraduation, nounGRE, nounGreek, nounhall, nounhall of residence, nounhaze, verbhigher education, nounhomecoming, nounhonor roll, nounhonours degree, nounintercollegiate, adjectiveintramural, adjectiveIvy League, the, adjectivejoint honours, nounjunior college, nounlectureship, nounLLB, nounLLD, nounLLM, nounMA, nounmagna cum laude, adjectivemajor, nounMaster of Arts, nounMaster of Science, nounmaster's, nounmaster's degree, nounmatriculate, verbmature student, nounMBA, nounMEd, nounmedic, nounmedical school, nounMFA, nounmidterm, nounMilitary Academy, nounminor, nounMLitt, nounmortarboard, nounMPhil, nounM.Sc., nounOpen University, the, option, nounoral, nounOxbridge, nounPhD, nounPhi Beta Kappa, nounpledge, nounpledge, verbpoly, nounpolytechnic, nounpost doctoral, adjectivepost-grad, nounpostgraduate, nounpostgraduate, adjectivepractical, nounprof, nounprofessor, nounprofessorial, adjectiveprofessorship, nounProvost, nounqualified, adjectivequarter, nounrag, nounread, verbreadership, nounredbrick, adjectiverush, verbrush, nounsandwich course, nounschool, nounsemester, nounseminar, nounseminary, nounsenate, nounsenior, nounsingle honours, nounsophomore, nounsorority, nounspring break, nounstate university, nounstudent union, nounsubject, nounsumma cum laude, adverbsummer school, nounsurvey course, nounsyllabus, nountech, nountechnical college, nountenure, nountermly, adjectivetertiary education, nountheological college, nounthesis, nounthird, nounthird class, nountutor, nountutorial, nountutorial, adjective2.1, nountwo-two, nounU., undergraduate, noununi, nounUniv., university, nounupperclassman, nounupperclasswoman, nounvac, nounvacation, nounvarsity, nounvice-chancellor, nounvisiting professor, noun a former student of a school, college etc:  a Crawford High alum
