Ways to tell them apart:
Both words imply destruction, but decimate originally referred to reducing something by a tenth, a much smaller scale compared to annihilation.
Annihilate suggests completely destroying something, leaving nothing behind, whereas decimate often implies severe damage or reduction but not total obliteration.
You can remember decimate by its root deci, related to ten, indicating a partial reduction.
Annihilate shares the root with nihil, meaning nothing, which can help recall its meaning of total destruction.
Use decimate for situations involving significant damage but not complete ruin and annihilate when referring to complete obliteration.
