Türkçe'de karşıtı bulunmayan bu zaman Türk öğrenciler tarafından kavranması oldukca güç olmaktadır. Bu zaman iki ögeden meydana gelmektedir. Birincisi aynen geniş zamanda kullandığımız şekliyle 'have' yardımcı fiilidir. İkincisi ise esas fiil olarak kullanacağımız fiilin ücüncü şeklidir.
Fiilin ücüncü şekli fiile -ed eklenerek yapılan Regular Verbs
