Just to address the original post: First of all, you are thinking of Zapf’s Law, not the Sapir-Whorf hypothesis. Zapf’s Law states that more frequently used words are shorter.
The Sapir-Whorf hypothesis is something that no linguist believes in anymore. It was an interesting theory in the day, but it’s no longer credible. Language does not limit thought, although it could make expression of that thought more difficult.
