Other Variable Aspects of Language
It's not only the sounds and meanings of language that vary. There are many other aspects as well.
Some languages tend to make very long words (like German), some tend to make short words (like Chinese).
Languages are structured around different word orders. Most, like English are Subject-Verb-Object
(S-V-O) or S-O-V, like Korean. But Yoda speaks O-S-V...and some are like that (mostly in the Amazon Basin).
Some aren't structured less around word order than around word endings (like Latin and Hungarian).
Languages vary in many other ways as well...
