As a native English speaker, and not knowing much in the way of spanish or its variants, I was curious as to what the five deaths actually mean when translated, if any of the below is wrong, let me know and please answer those I don't know:
Isla Matanc(c)eros - Suicide Island
Isla Muerta - Murder Island
Isla Pena - Pain Island
Isla Tacaño - Barren Island ( This one comes up as Stingy or Miserly, but I dont think this is the correct translation in English in keeping with "death", one cant die for being tight-fisted, So I'm assuming that Tacano is related to starvation or lack of resources?)
Isla Sorna - I don't know does this have some meaning?
Hi, I'm Spanish speaking. (From Chile)
I will comment a bit on the subject, although these names are written with a lack of spelling (something typical that can be confused from English to Spanish).
I will give some examples and / or synonyms of the names of the islands.
Isla Nublar: Island Cloudy, Fog, Cloudy, (There is a lot of fog in this place).
Isla Muerta: Death Island, Death, (There is no life in this place).
Isla Pena: Isla Penosa, Sadness, Phantom, Ghost, Purgatory (When people die and they become ghosts, you are ambulan by certain places, living people like you and me, In Latin America this phenomenon is called "Alma en Pena" <soul wandering aimlessly>). It can also refer to a penitentiary, when someone commits a crime, the judge will give a jail
sentence.
Isla Tacaño: Isla Tacaño, Egoista (Defined to a person who refuses to give something he owns, usually does not tend to spend money, some resource or thing that he has, prefer to invest as little as possible to save money).
Isla Sorna: Isla Ironica, Sarcasmo, (It refers to when people try to say something really in a tone of mockery, sarcasm.) Also depending on the context, one could say that it is about referring to the night, that when the night<as a jargon>; Comes, we will surrender to sleep, go to sleep).
Bring all this to the context of the Universe of Jurassic Park:
Isla Nublar: We are shown an island with a lot of fog in the beginning.
Isla Muerta: Not much is known about this.
Isla Pena: Not much is known about this.
Isla Tacaño: Not much is known about this.
Isla Sorna: In the movie, almost everything happens during the night.
