reversed

Reversed is the past participle of reverse and an adjective meaning turned backward or in the opposite direction, order, or orientation. It derives from Latin reversus, the perfect passive participle of reverti, and entered English with senses tied to turning back or overturning something.

As an attribute, reversed describes something that has been turned the other way around. This can refer to a physical orientation (a reversed image or mirror image), a sequence in the opposite order (reversed chronology or a reversed list), or a word written backward (a reversed string).

In computing and data processing, reversing means producing a sequence in the opposite order. Common examples include reversing a string of characters, reversing an array, or reversing the bits in a byte. In mathematics and physics, reversal often implies an inverse transformation or time-reversal symmetry.

In law, a court ruling can be reversed on appeal, meaning the higher court overturns the decision of a lower court.

Related concepts include reverse, inverted, backward, and palindrome for text that reads the same backward as forward. Reversed is widely used across disciplines to indicate the opposite orientation or order.
