What Is the Past Form of Now?
Could you tell me what is the past form of verb now?
Well, first of all "now" is not a verb. :)
It's actually an adverb.
If you want to refer to the past instead of the present you could use, "then" or "at the time."
"I am tired now."
"I was tired then."
"I was tired at the time."
And so forth.
