Hi, guys. I watched one of the "Lie to me" series and there was a conversation between, well, two characters. Emotion: smile

"You saw all the way through it, didn't you?"
"You saw right through it from a/the start ."

I'm bowled over a little because I can't distinguish it clearly because of his manner of speech. It was very fast.

What article is more likely? Thanks in advance.
"From the start" is an idiom, and fits your example. ("from the beginning")

"From a start" does not fit.

Sometimes we use the expression "from a standing start" in describing a race.
Oh, I see daylight now. Thank you, Avangi.Emotion: smile
