Volcanos or Volcanoes?
Your choice!
Volcanos
Exemple : ‘’I would love to visit all the volcanos in the world.’’
The plural of the word "volcano" is often an area of uncertainty. It can be spelt without an "e" as "volcanos."
Volcanoes
Exemple : ‘’The volcanoes in the region have not erupted for centuries.’’
In the same way as some other nouns ending in the letter "o" it can also be made plural through adding "es" and thus becoming "volcanoes."
