「Vte + iru (2) ~てうる」
"be ~ed," "be ~ing"
In contrast to the first iteration of Vte iru, which expresses an ongoing action, this expresses a state of being resulting from a previous action. Standard Japanese verbs that use this form are shiru 知る (learn, realize or know), motsu 持つ (possess) and oboeru 覚える (remember). In this specific verb form, these indicate states of "knowing," "possessing" or "remembering," usually represented in English by, in the first person, "I know," "I have" and "I remember." Also note that the opposite of shitteiru is shiranai (not shitte inai).
Ginkō wa sanji made aite iru.
The bank is open until three o' clock.
Toda-san wa akai doresu o kite imasu.
Ms. Toda is wearing a red dress.
Hara-san wa kekkon shite iru.
Mr. Hara is married.
Hope this helps!
