Learn English – Which is correct? How did it all began/begin

do-supportinfinitivespast-tense

I'm confused between these two. Which is correct to use between

  1. How did it all began? or
  2. How did it all begin?

Best Answer

Began is the simple past tense of begin. An example conversation using both of these is:

"How did it all begin?"

"It began when I first saw her face."

In the first sentence, because the verb uses the auxiliary verb "do", the past tense is conveyed by changing do to "did". An example in the present tense using "do":

"How do I begin this?"

"You begin by wrapping the string around your fingers."
