REMEMBER: plural nouns ALWAYS use the -en suffix on ALL the adjectives that come before them.
This is true for all cases (nom, akk, dat, gen) and all inflections (strong, weak, mixed), EXCEPT for strong inflections in the nom & akk (-e ), and gen (-er).
I had an "aha!" moment when I realized this. It definitely made adjective suffixes easier to remember.
We can't - it would need more context, like another sentence or pointing. A similar example in English - if a teacher said in the presence of a few kids "Your in trouble" the kids might naturally ask "who, me?" But context might tell you, the one kid holding a fire extinguisher is probably which "you" they mean
If you look up these words in the Duden, it specifies these words as synonyms. In actual usage, I get the feeling that "speziell" is used much in the same way as in English, for occasional events like birthdays, while "besonderes" is more like "specific (to someone or something)", so you might use it, for example, to describe someone's particular manner of speaking or acting. It's worth noting that "besonderes" cannot be used predicatively, but only attributively, meaning you can say "Das ist ein spezielles Getränk" (attributive) or "Dieses Getränk ist speziell" (predicative), but while you can say "Das ist ein besonderes Getränk", you cannot put "besonderes" after the noun, although you can add a "was" to make it work if you turn the adjective into a noun: "Dieses Getränk ist was Besonderes".
