(used of God) declare innocent; absolve from the penalty of sin
"In his mercy, God will justify every soul that turns to Him in faith."
To provide an acceptable explanation for.
"The manager had to justify her decision to cancel the event due to unexpected weather conditions."
In plain English: To justify something means to show that it is right, fair, or has good reasons for happening.
"He could not justify his spending so much money on unnecessary items."
Usage: Use justify when you need to offer a valid reason or defense for someone's actions, rather than simply describing the act of aligning text in paragraphs. This verb is often confused with validate, but while validation confirms truth, justification provides the underlying cause that makes an action acceptable.
The word justify comes from the Latin phrase justificare, which literally means "to make just." It entered English through Middle French and Old French with this same sense of rendering something right or lawful.
