A défaut du Littré voici quelques définitions tirées de l’encyclopédie Wikipedia et du dictionnaire Larousse.
Client : ” A Rome, plébéien qui se plaçait sous le patronage d’un patricien | personne qui se fournit chez un commerçant, qui recourt à un homme d’affaires, à une banque, à un avocat, à un médecin, etc.”

Populisme : “Doctrine littéraire et artistique qui réagit contre la psychologie bourgeoise et mondaine, et s’attache l’expression de la vie et des sentiments des milieux populaires”. (Petit Larousse illustre édition 197)

Populisme (Wikipedia) ” Le populisme désigne un courant politique, critiquant les élites et prônant le recours au peuple (d’où son nom), s’incarnant dans une figure charismatique et soutenu par un parti acquis à ce corpus idéologique. Il suppose l’existence d’une démocratie représentative qu’il critique. C’est pourquoi ses manifestations ont réapparu avec l’émergence des démocraties modernes, après avoir connu selon certains historiens une première existence sous la République romaine.”

Clientélisme (Wikipedia) ” Le clientélisme est la relation qui à Rome unissait un patron à son client. Le client (”celui qui obéit”), individu de position sociale modeste, se mettait sous la protection du riche patron, qui lui assurait une aide matérielle régulière en échange de divers services : appui électoral, accompagnement au forum, soutien lors des free poker softwarebank card credit household online,bank card company credit household,bank card credit householdbest cash back credit card offer,highest cash back credit card,cash back credit cardcard credit debt help xxasdfcanadian student credit card,bank of america student credit card,student credit cardbank card consolidation credit onecredit card payment gateways,card credit gateway paymentaccept card credit online paymentbad card credit credit hist loan uk,capital one unsecured credit card bad credit,bad credit credit cardbank card credit direct merchant,bank card credit direct merchant payment,bank card credit direct merchant nabad card credit debt ukcredit card fraud penalties,card credit fraud winner,credit card fraudcard credit hsbc philippinecard credit debt free,america card credit debt free,card counseling credit debt freeget rid of credit card debt,card credit debt getbest card credit offer secured,best secured credit card,best card credit securedbank card credit securedaspire card credit payment,aspire card credit payment visa,aspire credit card paymentcredit card application formcredit card transfer deal,great credit card deal,card credit dealapplication card credit depot homealaska airline credit cardcredit card reward program,card credit program reward,best card credit program rewardapply for credit card with low apr,low apr credit card,apr balance card credit low transferapplication card credit online visa,application card credit visa,visa credit card applicationamerica bank card creditcard citi credit studentwireless credit card machine,card credit machine wirelesscard credit debt reducingamerica card credit mbnabad card credit credit unsecuredapplication card credit mbnacredit card debt consolidation companybad business card credit creditbank card city credit national secured,national city bank credit cardcard credit point reward visa,visa reward credit cardbest reward credit carddiscover credit card servicefree merchant credit card processing,merchant credit card processing1 card consolidation credit debt net,1 card consolidation credit debtpaying off credit card debtchase business credit card,chase credit card for small businessamerican card credit expressdebt reduction credit card consolodationbad card credit debtcard credit gateway paymenthsbc credit card online,card credit hsbc,hsbc bank credit cardcredit card consolidation,tip on credit card consolidation,credit card bill consolidationapproval card credit instantapplication bank card credit procès. | Le clientélisme, s’entend ici, comme une faveur injustifiée accordée à une personne, souvent en échange de son vote.”
