Why This Is The Most Popular Peel And Stick Wallpaper

Modern french mostly uses /gz/, as in xénophobie, but i don't know the history of how the modern french. What part of speech is "why?" i think it modifies the verb "is", so i think it is an adverb. Why did the english adapt the name pineapple from spanish (which originally meant pinecone in english) while most european countries eventually adapted the name.

This seems the simplest and most elegant expression of the meaning.
