Would you please tell me which one is correct? And why?
Could you possibly elaborate your explanations freely or readily?
I get bored if I’m at home on my own all day.
I bore if I’m at home on my own all day.
"bored" is used as an adjective, and not as a verb. In the participle
"get bored", get is the verb and bored is an adjective. If the sentence were
"Sitting alone at home all day _bores_ me", bores is a verb. This is why
"I bore" is grammatically on the grey side. The verb form of bore would mean the act of drilling holes.
