Latin is used for scientific names because

a) It is a dead language

b) Scientists can communicate more clearly

c) Both of the above

The answer is b) scientists can communicate more clearly, because for one, Latin is not a dead language, and two, scientists need to communicate with other scientists around the world. There are quite a few scientists around the world, obviously speaking Latin, who make huge discoveries daily, so this is an important language to use.

B. Scientists can communicate more clearly.

Since all the names are the same languages barriers won't stop scientists from research or collaborations with other scientists around the world.
