Lightened

The sky lightened as it stopped raining.

The government lightened taxes.

The world is lightened by the sun.

Revolutions have never lightened the burden of tyranny: they have only shifted it to another shoulder.

Maria's eyes lightened with pleasure.

In the evening the sky became overcast with dark clouds; it thundered, and lightened, and the huge icebergs, glittering in the bright lightning, were lifted high into the air by the black waves.

The sky lightened after the storm.

They lightened your burden.

They lightened his burden.

They lightened our burden.
