| ngilizce'de sözcükleri rasgele bir araya getirerek cümle kurmamız imkansız. Bu nedenle her cümlede özne ve yüklem olmak zorundadır. İngilizce'de temel fiil, "be" (olmak) fiilidir.
"Go, come, study, eat, do" gibi normal fiillerin olmadığı cümlelerde yüklem olarak "be" fiilini kullanmamız gerekmektedir. Ancak "be" fiili, özneye göre şekil almaktadır. Örneğin, "be" fiili geniş zaman ve şimdiki zamanda kullanılıyorsa, I öznesi için "am", You, We, They özneleri için "are" ve he, she, it özneleri için "is" halini alır. Aşağıdaki tabloda "be" fiilinin çekimi verilmiştir:
