a once-in-a-life experience

[jasonlulu_2000]

"For me, this is a once-in-a-lifetime experience. "

When I write this sentence in my Word document, the computer indicates that I have made a mistake. It suggests that I should write" For me, this is an once-in-a-lifetime experience" instead.

So which one is correct? a once-in-a-lifetime or an once-in-a-lifetime experience

"Once" is pronounced as [wʌns)

Thanks for your help!

"A" is correct.

I"m shocked Word would suggest "an." It makes its share of mistaken "corrections" but that's not one I've ever seen before.
