A more thorough explanation:

e mera gratia

e mera gratia is a Latin phrase that means "out of mere grace or favor."

1. The company decided to give the employee a bonus e mera gratia for her hard work, even though it wasn't required.

2. The judge reduced the defendant's sentence e mera gratia because of his good behavior in prison.

The examples illustrate the definition of e mera gratia by showing situations where someone receives something (a bonus or a reduced sentence) not because they earned it or it was required, but simply out of favor or grace. In other words, it's a gift given out of kindness or generosity, rather than obligation or merit.
