My best lines are never fully on purpose. Story of my life, I’m starting to enjoy it.

#3 a lot of ét- words in French are also the equivalent to st- in English. There are exceptions in both cases.
#7 English has: “Buffalo buffalo Buffalo buffalo buffalo buffalo Buffalo buffalo”
#10 there is no “Elvish” language in Tolkien. The Quenya language is indeed partially based on Finnish but also Latin and Greek. The Sindarin Elvish language, which is more contemporary to the LOTR setting, is more based on Welsh.
#14 Japanese doesn’t have a future tense either, in the sense of conjugation.
#18 Irish sign language too, much easier to communicate with US or French SL speakers than right across the Irish Sea.
Nitpick: The name of the fruit came first, then the color.
Food etymologies are interesting. The Arabic naranj itself came from India. However the most common current term for orange in Arabic is burtuqaal, because they were brought by Portuguese merchants. Arabic also uses burtuqaal for the color too.

Lots of dialects have /g/. /p/ is much less common, but does exist in some places.
That will show me not to generalize starting with a sample of one! 
You’re entirely correct about fuṣḥā Arabic / Classical Arabic / Modern Standard Arabic.
