nouns whose ends are "o" should be followed by "es" or "s"

[terrenziqq]

The plural of "tomato" is "tomatoes".
The plural of "patato" is "potatoes".
But the plural of "photo" is "photos".
And the plural of "pomelo" is "pomelos".
and such examples between "s" or "es" added are too numerous to be cited...
So, is there any certain rule to follow?

Don't add an 'e' to Italian or Spanish word like: piano, cappuccino, sombrero, burrito.
Otherwise, I can't help.
