Shumaila Saeed
By Shumaila Saeed || Updated on December 25, 2023
Decimate originally means to reduce by a tenth, often used for significant but not total destruction, while annihilate means to completely destroy or obliterate.
Decimate vs. Annihilate

Key Differences

Decimate comes from Latin "decimatus," referring to the Roman practice of killing one in ten soldiers for discipline. Annihilate derives from Latin "ad nihilum," meaning "to nothing," indicating total destruction. Both words have evolved, but their origins reflect their distinct meanings.

Decimate implies a substantial reduction or damage, but not complete destruction. It's often used in the context of populations or resources. Annihilate suggests total eradication, leaving nothing behind. This distinction is crucial in understanding the scale of destruction each word conveys.
