~なくなる (cease to)

Because thunder is now scientifically explained, people no longer believe it's the wrath of god against humans. So thunder isn't as frightening as it used to be.

Something unexpected has come up, and I'm sorry to say I can't meet you on February 27 after all.

If you don't keep your promises, nobody will take you seriously, I'm telling you.

Once it's out of sight, it ends up forgotten for good.

She wears thick glasses and is afraid of going blind.

When I woke up, my suitcase was gone.

If you put cotton mittens on the baby, it'll stop scratching its own face.

A fallen tree had blocked the road.

She stood there even after the train was no longer visible.

After that, the pain never went away.

A rockfall made the only road to the village impassable.

You'll lose your friends, you know.

Come back when you run out of medicine.

At night there was no more foot traffic.

The riot became uncontrollable.

The plane disappeared from sight in the blink of an eye.

The airplane disappeared into the clouds.

The airplane was no longer visible.

I watched until the airplane was no longer visible.

The sad news made him lose his appetite.

She could no longer stand his rude words.

Since having a baby, she hasn't gone out much.

She's outgrown her favorite dress, so it needs to be altered.

She vanished into the crowd.

She no longer knew what to do next.

I caught a cold and lost my voice.

The plane disappeared from sight shortly after takeoff.

The plane flew away and disappeared from sight.

The airplane soon disappeared from sight.

She was sick, so she became unable to come.
