The verb "know" in the perfect and continuous tenses

Post by Jededly »

Hello,
Is it possible to use the perfect tense in the cases,"After your answer I have known that I'm not quite right" or it always should be "After your answer I knew/Iknow that I'm not quite right"?
Also, could one say,"After your answer I'm knowing that I'm not quite right". Is it possible to use the present continuous tense for "know"?

Although the verb 'know' cannot be used in continuous tense-forms, the present perfect might occur in a sentence such as

I have known many interesting people in my life.

implying that you no longer know them (i.e. no longer meet/keep company with them).

However, to denote present knowledge, only the present simple is used, hence e.g.

Having heard your testimony, I know that he is lying.
