Where do interwiki links belong/what is the correct interwiki syntax?
Interwiki links appear in one of two places: either at the very end of the article, or embedded in a translation table. Interwiki links at the end of the article follow “normal” interwiki syntax: [[ followed by the (usually two-digit) country code, then a colon, then this same article name (identical matches ONLY!) followed by ]]. For interwikis within translations, (say in the translation table of the English article cat,) you would normally list first the English Wiktionary’s wikified link; chat, as [[chat]] to allow your readers to learn about the French word (by reading the English description of it) then the French version of the French word is linked as chat by entering [[:fr:chat|chat]].
