So, I looked up the other names for grant, and I think I am on to this.
So first off. All of the translations relate to pomegranates.
So, why Lino in Europe?
Carl Linnaeus, the European botanist whom named the pomegranate.
The Hebrew word for pomegranate tree and fruit is rimmôwn or rimmôn derived from the root râman which means to exalt, or lift or get (oneself) up, or to mount up. Of which Linneus named it after given it was a symbol of hope, and "uplifting. This works well with Grant's rockclimbing background. This is a very clever play on words if I am correct.
Pomegranite also has a double meaning, which refers to the pome"GRANITE" or a type of rock, which also ties into the rock theme.
Lastly, on Lino, after Linnaeus, we could speculate if also references "LINOleum" a hard rock-like surface.
I am
almost certain that Grant is a rock type.
I will do my research on the other names and see if there exists a common thread. Perhaps to plants.
Lemon and Viola (A fruit and flower) may have a similar method of naming.
Okay, now for Clemont:
This time they all reference lemon or citrus fruits in the name.
But, that doesn't help us figure out his typing. Though, CiTRON could reference electron or electronic.
Clemont is really the name that sticks out. I finally figured out, Nicolas Clement. Another famous scientist. He was the scientist that discovered the measurement of a calorie and energy, which alludes to electronics. Also, tying into this, is the calorie, which ties into the fruit calories. Further, Clemont did research for sweetening companies, which also ties into the allusion to sweet lemons.
I have concluded, that Clemont is very likely to be an electric gym leader.
If both of my findings are correct, then Gamefreak is focusing on scientists and researchers of some sort, as well as fruit/plants in naming the gym leaders.
