這些同義詞都可以用來表示各方之間的協定或協議，但在具體用法上有所區別。，pact通常指或實體之間的條約；accord強調雙方的一致意見和共識；understanding強調雙方對某事物的理解和認可；arrangement指安排好的計劃或協議；而contract則是指正式簽訂的合同文件。

筆者jack認為，agreements乃雙方所達成之共識，或共同決議也。此等語可用單數形式（agreement）抑或復數形式（agreements）皆可。此語可與他諸如pact、accord、understanding、arrangement和contract等詞連用，然而在具體用法上則有所不同也。總之，agreements乃一事實，而非虛妄之談。
